Non-Profits have different filing requirements. If you are a 501(c)3 organization or something of the like then you file a form 990 or 990-EZ and all of the income and expenses for the non-profit are entered there.
Personal expenses for items that you have donated to the non-profit that you run are considered charitable donations and are entered as itemized deductions on schedule A. You will need to have a receipt for everything that you enter there as a donation to the charity.
Most folks still use the standard deduction even if they make charitable donations because they don't itemize their deductions.
Here is some information on non-profit tax filing.
