We have the same issue. Any resolution?
We are talking to TT customer support (TTCS) - they are not finding any know issues.
TTCS is not able to identify "ResidenceForeignCountryCd" data field in IRS1116.
Asking TTCS to report issue.
Obvious issue - "TT no error review" does not catch IRS error, i.e., not 100% accurate.
It may be that the error is in the data packaging for submission.
