How to fix error "Foreign Tax Credit Comp Wks: Excluded FEI - Dedns must be entered"

during the final review I receive a "Check This Entry" message for the "Foreign Tax Credit Computation Worksheet", Part III Foreign Tax Credit Computation, line 12 a (1) and (2).
These boxes are empty and the message says "Excluded FEI - Dedns must be entered" resp. "Total FEI - Dedns must be entered"

I didn't have this worksheet in my return last year which was prepared by a professional. I cannot find this worksheet in the IRS instructions for form 1116. If this is a worksheet it's usually not submitted for the final return.

how can I fix this? what needs to be entered here?
