I have 3 1099-Q's to enter. The first one had a payer name of "State of Rhode Island CollegeBound 529" and this one have me the error. I entered the second one as "State of Rhode Island CollegeBound" as I forgot to type 529 in the field. The second one did not get the eoor. I then went back to the first and removed "529" from the Payer name and it went through. I now added "529" to both and it is working......
With all that said, I think you are correct about something with the rounding being off.
