Agreed. This is very disappointing in that there is no way to do year-end tax planning, deciding whether to do roth conversions, make employer 401k contributions from my self employment, without knowing the trickle down effect on QBI, taxes, MAGI and how it affects my medicare costs, etc. Turbotax should at least put out a "tentative" program to enter estimated investment gains, self employment schedule C expenses, etc. so you can run sample returns.
