I learned from a CPA that if the foreign tax is paid to multiple countries (vs. a mutual fund listed as RIT), you must mail rather than e-file tax forms. The reason is that such forms must be checked manually by the IRS.
I don't think that there is any way of avoiding this annoyance which is created by the IRS and not TT.
It is my impression that the IRS will reject returns missing the 1116 form which, I think, is the simplified one.
