Thanks, again, AmyC. Per your inquiry: I am on the Windows Download version (not the On-line version). I can definitely see the correct form in the Forms section (AZ Form 221 Page 2: Annualized Income Installment Worksheet). Part A of the form (Calculation of Underpayment) is filled out and Page 2 has the same yellow cells waiting to be filled out. I cannot seem to find how to fill it out in the Step-by-Step, though.
