If I am a resident in AZ and made contributions to my grandchildren’s 529 plans in AZ, where do I list these on my return?

[KrisD · Accepted solution]

Enter the contributions on your Arizona State return. TurboTax should ask about that during your State tax interview. 

"Over 30 states, including the District of Columbia currently offer a state income tax benefit or tax credit for 529 plan contributions. In most cases, the taxpayer must contribute to their home state’s 529 plan to qualify for a state income tax benefit. However, there are seven tax parity states that offer a state income tax benefit for contributions to any 529 plan:

• Arizona
• Arkansas
• Kansas
• Minnesota
• Missouri
• Montana
• Pennsylvania"
