TurboTax transfers data from your federal return to your state return. Before you begin troubleshooting your state return, go back through your federal return and make sure everything is correct with the W2G.
After you review your federal return, select the State Taxes tab and review the state section. Pay close attention to the information, especially if you have made changes to your federal return. There might be new sections that need to be completed.
If this doesn't solve your issue, try deleting and re-entering your form.
