Are you trying to change data you entered ---like your income, etc? You have to prepare an amended tax return in order to do that. If you only want to change your address, then you need to file a change of address form with the IRS--and perhaps the state----in order to do that. You do not go back to the already filed tax return and change the address you entered on it at the time that you filed.
Or do you need to change the information in your TurboTax account?
Please be clear here about exactly what you are trying to change.
