I agree with original poster - I have on idea where this amount came from and turbotax wants an explanatory statement for it. I'm claiming a standard deduction. I don't have anything like alimony. The foreign tax credit carryover adds up to all the foreign tax I paid so it's not a part of that.
The amount is small - I may just change it to 0 as I can't explain it, and it's April 18.
ChatGPT gave this answer - informative but not conclusively helpful:
Line 3b of the Foreign Tax Computation Worksheet is used to report foreign taxes that are not eligible for the foreign tax credit. The amount reported on this line is typically the foreign taxes paid or accrued that do not qualify for the foreign tax credit, such as foreign taxes on income that is excluded from U.S. taxation or foreign taxes that are considered a deductible expense for U.S. tax purposes.
The amount reported on line 3b of the Foreign Tax Computation Worksheet may be carried forward to other forms or worksheets in the tax return as appropriate.
