I have that same problem with my Iowa error, it tells me that my gross receipts are over that $250k and can't efile, but when I go to the 1065 p5-8 sch C (BAR) looking at past 2021 that has it where it is 100% without the column A or B filled in.  They have made it very difficult to do this year for that.  Playing around with it.  So right now my example is they've automatically imputed in Column B line 1 $x amount, so should I put that same amount in Column A as $x too to make it the 100%?
