Thanks. I called no less than 3 tax experts, so far. The advice was to wait until a certain form that links aggregation with qbi would be available, so I will wait a while, even there are some reports here that the form is available and folks were able to efile... the mailing is possible but the whole point of TT is convenience. I spent so much time and energy this year that an in person CPA would have been a much wiser choice...
