Last night I was able find somebody in support that understood the "big" issue here. It is not about finding my error or even how my taxes can get filed on paper. The real issue is that everyone e-filing a 1116 form will hit this error.... which could be 1000s or more. Spending an hour on the phone and telling then to not e-file will be a huge drain on their resources and make customers "dissatisfied". Many of us have larger returns and live in foreign countries and really appreciate e-filing.
There is a case open to fix their problem with the form. They added my email to the notification list for this bug fix. If more people complain and get added to the list then the priority may increase.
My current suspicion: IRS changed the "schema" (formal electronic format) on form 1116 (specifically the Date in section II) and introduced an issue. It does not appear that the IRS will change this for 2020 because they published a work-around for companies that submit electronic forms. Turbotax has not implemented this work-around.
