How does Turbotax automatically calculate Gross Income from all sources on the Form 1116 3e? There is error in automatic calculation. My Mac does not open data source.

Thanks for this - I was able to use your outline to back into the calculation for 2021. In my case, for the K-1 partnership income, line 16 code B and line 1 are VERY different. Do you know why TT would choose to use only the foreign income (line 16 code B) in lieu of the total income (line 1)?
