TurboTax transfers data from your federal return to your state return. If the info in your federal return is incomplete or incorrect, your state return won't be complete or correct either.
Before you begin troubleshooting your state return, go back through your federal return (starting at the Personal Info tab), and focus on the entries made to the 1099-R to make sure everything is correct.
Once you're done, select the State Taxes tab and review the state section. Pay close attention to the info, especially if you made changes to your federal return. There might be new sections that need to be completed.
Sometimes changes made to your federal return won't transfer if you override info in your state return. If this happens, delete your state return and start over.
