For the "ForeignTaxesPaisOrAccuredDt" error, it does not seem like this could be caused by "wrong" amounts. This error message is clearly referring to a specific XML schema field while parsing the e-file data. "Dt" is date.
It is possible that some import of a 1099 brings the date in wrong/right/different (without the field checking of TT). For some people that have the date imported as a text field, changing it to 12/31/2020 can fix their problem.
I'm in the group where the data was not imported at all. I entered foreign taxes paid for my salary and it shows up in 1116 Comp Wks. That data goes into Form 1116 (COPY 1) and Form 1116 AMT (COPY 1). The date has always been 12/31/2020 and this is rejected.
