I am in the same situation on the Turbo Tax error message to reattach form 1116b.
I have tried all user suggestions.
Yes e-filing Federal first or only works the first time you efile.
But I, like other users, am trying to amend. the amendment has nothing to do with 1116b,
but I have tried deleting the form and the worksheet and then reentering the information onto the worksheet.
Error message returns.
Oddly, and perhaps more important. (I watched this very closely as I have been through the above procedures several times.) TT changed my election to use itemized deductions instead of the standard deduction-without me replying to do that on the step by step view. TT went to my personal information and unchecked a box - the one that says I am married filing separately and my spouse is itemizing. The fix is to recheck this box. Then one has to do another fix- the charitable cash contributions shows on a line of the 1040 (ok) but then the portion to be deducted in addition to the standard deduction (which I am not taking) shows as a zero. TT shows an error message until you change that zero to a blank, by using delete.
ALL of this is buggy with NO workaround on "reattaching schedule 1116B" other than to send in a paper return. Mind you the IRS is a few years behind on paper. PLEASE fix the bug.
From what I can tell the other users suggestions work to efile Federal only and the problems come with Amended Federal returns.
