Double-check what CDOR thinks you submitted.
TT has a bug with the Easy-forms for 529.
It never queried me for the 529 account owner in the Easy forms section. Going down into the actual raw 104 forms, that info was missing. I logged onto CDOR and noticed my refund was off by a lot, and the 529 Contribution form (104AD) was NOT submitted. I had to amend the return through CDOR. CDOR must have rejected the 104AD form when TT submitted all my data.
