TurboTax does not store your bank information. The only bank information that is available to the IRS is what was entered on your federal tax return for a direct deposit of a federal tax refund.

If you do not receive any other stimulus payments by January 15, 2021, then the stimulus payment for which you are eligible to receive will be entered on your 2020 federal tax return as a tax credit on Form 1040 Line 30.
The TurboTax program will ask about stimulus payments in the Federal Review section of the program.
