Have a similar problem. After the final 1116 Form was added on March 3,2022(for 2021 return, Form 1116 worksheet shows error in sum of Foreign Credit Tax Carryover, both AMT and Regular totals.
This line is populated by turbo Tax. Checked the total shown and it is correct.
Sounds like there is a problem with the program. sure cannot correct this as e filer.
