So, I just increased the "added income" to the point that it ensured I wouldn't be getting a refund! DUH!! Didn't have to do any special navigation (but thank you both for the instructions). In the end, it was just a few screens of "continue" before I could zero out line 18 and then wrap it all up. Went back and deleted the "added income" and voila, worked like a charm!
Thanks again and sorry for my brain freeze!
