Your post isnt wrong, but you just have to keep in mind that for the huge majority of people in the US, keeping receipts of small donations is pointless, becuaee they will never exceeded the standard deduction, which ever filer gets. As an example, the 2025 standard deduction for single filers in 2025 is 15,750.
So unless all your deductions and other deductions exceed that amount, you should be taking the standard deduction anyways, and all the receipts count for nothing, and are a waste of time to enter.
