I was told a tax form would be generated after I made the contribution (which I made in early February) but got nothing. I just printed a statement showing my contribution, highlighted my contribution, and mailed it to the State with my State tax forms. According to the Iowa DOR refund status, my return is "in process" so I am assuming that it worked fine.Anyone happen to know if anything special has to be done to "declare" Iowa 529 plan contributions made in 2019 (before the April 30 deadline) in order to claim the deduction on 2018 state filing? Can't find anything on that, other than it is allowed.
