Does anyone know where to update bank info? TuboTax instruction is to go to "File", but there isn't a place for me to update my bank info for refund.

Yes, you will change a bank account number in the filling stage of your tax return.

If you proceed to File on the left sidebar

1. You will proceed through the interview
2. There will be multiple security questions
3. You will finally get to the point to edit or remove the Bank Account
4. You can then decide how to pay, and request a direct deposit.
