where do I enter donation to a 529 fund?

[Hal_Al · Accepted solution]

For most people, you don't enter it, at all.  There is no federal deduction for making a contribution to a 529 plan, so there is no place in the TurboTax (TT) Federal program to enter it.  TT will not be tracking your contributions.

Some states allow a deduction on the state return. If your state is one, it will come up in the state interview; usually in the "Here's how (your state) handles income differently" section.  If your state allows a carryforward, the TT state program will track that.
