Form k-1 box 16 code a and form 1116 wks partnership

[earlyride5372]

I have entries for box 16 codes A, B, Z and AE. I get an error when I enter the amount for code B, but Turbo Tax doesn't tell me what that error is or how to correct it. I believe that it is looking for a form 1116 and I already have many separate 1116 forms. How do I make this correction?
