Where to list Tax Overpayment?

Hi. If I paid $1000 for my 1040 in February using Pay1040 and then when I do my taxes in April, I realize that I don't actually owe any taxes for the current year, where on the form 1040 would you list that $1000 to get the refund? I see on line 26 it says "2021 estimated tax payments and amount applied from 2020 return", but I don't see anywhere to list if you made an overpayment for the current year?
