Once you have sent your tax return to the IRS and it has been accepted by the IRS, it's out of TurboTax's hands. There is absolutely nothing that you or anyone else on the planet can do to change anything. You're basically done.
Now if you realize you made a mistake, then you will have to wait until the IRS has processed your return and you have physical possession of any refund you may be due, before you can amend the return. Until then, you sit and wait. There's no other option.
