Seems to be a programming issue with the IRS "Where's My Payment" web site. It does not like the "0" amount nor does it understand not checking "Refund" or "paid". If you try to populate values, it knows they are incorrect. Also since some of the lines from line 8b of the return can go negative, wonder how it feels about those values...
Makes you wonder who actually programs this stuff (not the quality of Turbo Tax software...!)
