I just found out that I overpaid my taxes by a significant amount last year.
I suppose I need to file an "amended return" in order to get my money back.
The problem is that if I just fill out the new return, it will show what I should have paid, not what I did pay. How do I enter what I paid, so I can get back the difference? I looked in the "Payments" section of the 1040 and nothing listed is "amount you already paid", except withholding but this is not withholding.
