IL1040X software error. On line 33, TTax does NOT enter original overpayment, but the amended one. I override its entry, but it reverts to incorrect entry when printing.

IL1040X software error. On line 33, "Overpayment, if any, as shown on your original Form IL-1040, Line 30",TTax does not enter original overpayment, but the amended one instead. This results in no refund. I override its entry, a correct refund shows, but it reverts to incorrect entry before printing. Solution?
