Private Foundation Deductions - private taxes and 990-PF

[doxiemom801]

Background: I started a non-profit dance company in 2024 and I am the director.  It is classified as a private foundation.

I did invest my own money to buy their first costumes for their first performance.

Question:

Can I write off the amount on my private taxes that I spent buying costumes, since it was a donation to the private foundation, even though I am the director?

Do I need to also disclose this amount on the 990-PF when I fill this out, since I did not directly benefit from the donation?
