I had the same problem. It comes from a carryforward of foreign tax credits from your past brokerage 1099 statement(s) in the foreign tax paid box. TurboTax should have allowed you to deduct the amount from your tax due. The TT software does this for the current year's 1099 but for some reason did not do this for some years in the past (in my case 2018). Usually this is a small amount and you can easily forget it. Go to "forms" and scroll down to "1116 comp wks." If the numbers are small enough in line 10 and below that in the carryover chart, zero them out by deleting them so that the total carryover to 2022 and AMT carryover to 2022 (both at the bottom of the worksheet) are blank, this will solve the problem and you can file your return.
