Captain Tom's daughter has admitted pocketing £18,000 for judging a charity award and handing out a plaque while the foundation set up in her father's name received just £2,000.
Hannah Ingram-Moore and the charity - Captain Sir Tom Moore Foundation - are now being investigated by the Charity Commission.
Ms Ingram-Moore was paid by Virgin Media to attend and judge 'The Virgin Media O2 Captain Tom Foundation Connector Award' at the Ashton Vale Club for Young People in Bristol last year.
Details of her appearance came to light in the last week - after she admitted accepting the fee while still the foundation's boss in an interview with Piers Morgan in October.
She said: 'That relationship with Virgin Media started way back in 2020. My father was paid to be a judge, and judges are often paid.

'I was doing it with him, because of course he couldn't do it by himself.
'That relationship continued and they asked me to keep working with them.
'All of those discussions were happening even before I was imagining being interim CEO. So those plans were already in place.'
She added: 'I think in hindsight what I should have done was stalled that relationship with Virgin O2 to afterwards.'
According to BristolLive, Ms Ingram-Moore said: 'Ashton Vale Club for Young People is so deserving of this award as they proved to be a vital lifeline during the pandemic.
'At such a distressing time for many, they ensured a community remained as one.'
The Ashton Youth Club received £5,000 worth of technical equipment for its work during the Covid pandemic.
The Captain Tom Foundation will close forever when the Charity Commission investigation is over.

Ms Ingram-Moore and her husband were hit by an expensive fee after losing an appeal to keep their spa complex

Barrister Scott Stemp confirmed the charity's future at a Planning Inspectorate hearing to determine whether the family would have to demolish an unauthorised spa pool at their £1.2million home.
The Charity Commission has been investigating the Captain Tom Foundation for potential conflicts of interest.
Ms Ingram-Moore and her husband were hit by a large fee after losing an appeal to keep their spa complex - with neighbours unhappy about their illegal £200,000 pool house.
Ms Ingram-Moore and her husband Colin applied for permission in 2021 to build a Captain Tom Foundation Building in the grounds of their home in Marston Moretaine, Bedfordshire.
The L-shaped building was given the green light, but the planning authority refused a subsequent retrospective application in 2022 for a larger C-shaped building containing a spa pool.
The Captain Tom Foundation building was given an enforcement notice in July by Central Bedfordshire Council that it should be demolished as it was a 'now-unauthorised' building.
Officials have since dismissed an appeal against its demolition, with inspector Diane Fleming saying the 'scale and massing' of the new building - which has not been finished - 'resulted in harm' to The Old Rectory, the Grade II-listed family home.
Captain Sir Tom Moore went on to write three books under a deal with Penguin Random House that has earned his family more than £800,000
Ms Ingram-Moore also recently broke her silence on the £85,000 salary she earned as interim CEO of the Captain Tom Foundation. She also received £7,602 in expense payments for travel and administration between June 2021 and November 2022.
And last month a PR worker who helped launch Captain Tom Moore's charity complained about being 'cut out' by the family and told not to speak about her contribution.
Daisy Souster said she helped draft the press release announcing the veteran would be doing laps of his garden in Marston Moretaine, Bedfordshire to fundraise for NHS Charities Together. He would go on to raise more than £38million.
The 31-year-old also said she set up a Just Giving page and ran the Captain Tom Twitter page for the first couple of weeks when the story broke and quickly became a nationwide sensation.
But the University of Northampton graduate said her 'amazing experience' soured when she claims Hannah Ingram-Moore, Captain Tom's daughter, froze her out.
She wrote in a LinkedIn post: 'It was such a special time but I had to cut ties with the family when they cut me out and told me I was no longer able to talk about the work I had done.
'I would like to make it very clear that initially the family were extremely supportive of me and thankful for all that I had done, but for reasons unknown to me, they changed.'
Captain Tom Moore's daughter and her husband also insisted the family were right to keep £800,000 made from three books written by the lockdown hero and wouldn't do anything differently because it was 'his wishes'.
Hannah Ingram-Moore insisted the books were 'never anything to do with' the Captain Tom Foundation.
She said there was nothing in the contract that referred to the charity, nor was there ever any agreement that cash from her father's book deals would go to charity.
MailOnline has contacted Hannah Ingram Moore's representatives for comment.
