You'll be able to enter the contribution to your daughter's 529 plan during the state tax interview if your state offers a tax break. Not all states offer a deduction; for example, Maine no longer gives a deduction for 529 plan contributions. Also, the state may not require that the contribution is for a person who is claimed as a dependent on your tax return, so a contribution for your nondependent daughter may still qualify. TurboTax will ask questions to see if you meet the requirements or not.
The exact screen(s) where you'll enter this information depends on your state. The screenshots below provide examples of the first screens for 529 contributions for Indiana (TurboTax Online) and Massachusetts (TurboTax desktop software).
