You can't file your tax return twice, but you can amend if you need to. If your return has
already been accepted by the IRS then you will have to amend your return to
make any changes. You should wait until
you receive the original refund or until payment has been processed if you owed
on original return. See the TurboTax FAQ below for instructions on how to
amend your tax return in TurboTax
