If your return has been filed & accepted, you cannot change your banking information in TurboTax. You can only use the IRS Get My Payment, if the IRS does not have your banking information. If your banking information is wrong, you will be mailed a check.
Use the "Get My Payment" application to:
- Check your payment status
- Confirm your payment type: direct deposit or by mail?
- Enter your bank account information for direct deposit if:
- We don't have your direct deposit information and
- We haven't scheduled your payment yet
