We are not sure why you are telling us that your bank account is different.
The only time you can change banking information in TurboTax is when you are ready to file your next tax return---then you can enter banking information in the FILE section before you file. There is no other time that you can enter new banking information here to submit it to the IRS. The only time banking information goes from TurboTax to the IRS is when you file a tax return and enter the information during the filing process.
If the banking information you entered on your tax return for your 2020 refund is now incorrect, then the refund will be sent back to the IRS and the IRS will mail a check to the address on your tax return.
If you are referring to an Advantage account that you will use to purchase your 2021 tax software:
