Also struggling with Michigan pass through entity calculations not being supported.  Have done two returns so far, had to override add back and subtraction on Schedule 1 plus totals for each line, and also had to override credit line 30, Total refundable credits and payments line 34, Lines 36 you owe, Line 37 overpayment and override penalty calculation.

These overrides will cause returns to be paper filed if I am not mistaken.  It's one thing for ProSeries  to not support the line, it's a whole other issue for data entered to not be included in any calculations forward on the return.  

Is this something ProSeries will fix in short order, or is this what is expected to remain in place for tax season?
