Unfortunately, you
can't change your address if your return has already been accepted by the
IRS. If your return is rejected for any reason, you can go back into TurboTax and
change the address then.
If you are getting a
paper check in the mail, the check will be returned to the IRS and you will
need to change your address with them. Here are the instructions to change your
address with the IRS IRS
Form 8822 Address Change.
You will also need
to contact your state.
