TP will be filing the return on or before June 15, 2022 (automatic 2 months extension) but he already paid the balance due (the total tax) on Line 37. Can TP enter the amount paid on April 12, 2022 on Line 26 of Form 1040. Or such payment should not be reflected on Form 1040 as it is the payment of 2021 balance due Line 37.
