Does the amended return show you owe 1,000 on line 20? Is the first tax due on line 16? Did you pay the 1,000 based on the 1040X line 20 or did you get a voucher to pay 1,000? You should not use any vouchers that print out. Ignore the 1040V. That is for the original return or what the original return would have been if it didn’t need correcting. Don’t pay the amount on the 1040V. Pay the amount on the actual 1040X.
