After filling out the Foreign Tax Credit form and going to finalize my return, I get the following screen:
Form 1116 (COPY 1) -- Explanation Stm: Detailed Explanation must be completed. Enter your explanation here to complete the required statement. It must show the other deduction items for line 3B column a.
What do I put here?
Your Form 1116 Explanation Statement for line 3b should be a description or a breakdown of the item(s) reported on Line 3b.
How do I know what to put there? TurboTax filled that form in for me, and it didn't explicitly ask me about any deductions for the foreign tax credit.
It depends. Are you claiming your foreign tax credit as a deduction or a credit?
