Since your tax return has already been filed, you cannot go back and make changes. You will need to file an Amendment to correct your State Tax Return.
TurboTax can help you file the Amendment, if needed. Use this link for steps on how to amend your state tax return.
To find out if you’re owed an additional refund, compare your refund/balance due amount from your original return with what you see after you prepare the amendment in TurboTax.
