I also have this problem. In my case, the difference between TT's calculation and mine is about $10k. It's not clear if that is causing an error in the foreign tax credit. And I agree that the TT instructions for this Line 3eA are flawed. As to social security, I believe the amount to include is the total amount (Form 1040 Line 6a) rather the taxable amount (Form 1040 Line 6b). Similarly, I suspect the intent is to use Form 1040 Line 5a rather than 5b. Finally, for the references to Form D, it's not clear how losses are handled. I sure wish TT was responsive to these kinds of problems.
