The State of Arizona provides an annual Arizona state income tax deduction for 529 plan contributions of up to $2,000 for individual tax filers, and up to $4,000 for married couples filing jointly.
To enter a 529 Plan contribution in TurboTax, look for the screen in your Arizona return that is titled "Any Income Adjustments?" and select the option "I have a 529 Plan." See the sample screenshot below. You will then be brought to a screen where you can select if you made contributions to the 529 Plan. See the second sample screenshot below. After that, you will be brought a screen to enter your 2018 contribution amount.
