If you have not yet filed, you can update that by doing the following:
- First, sign in to My TurboTax.
- Next, click the orange Take me to my return button
- Once inside your return, click File in the top right
- Complete Step 1 if you haven’t already
- Then, click Revisit or Start next to Step 2
- Ensure In my bank is selected, then click the blue Continue button
- You may update your Bank name, Account type, Routing number, and Account number on this next page.
If you have already filed your return and it has been accepted (or mailed), it's too late to change your bank account for direct deposit. If this is the case, please see this TurboTax FAQ that answers “What if I entered the wrong bank account for direct deposit?”
