I dont remember what bank I used last year.when they sent my stimulas check it went into a bank account

Did you receive a refund anticipation loan or have your TurboTax fees paid from your federal refund or have your refund deposited to a TurboTax card? If you did any of those things, the stimulus payment went to the 3rd party banks that provided that service. Those banks will decline the deposit and the IRS will issue a paper check and mail it to you at the address on your tax return.

See what the IRS says:

To help protect against potential fraud, the tool also does not allow people to change direct deposit bank account information already on file with the IRS.

If we issue a direct deposit and the bank information is invalid or the bank account has been closed, the bank will reject the deposit. We will then mail your payment as soon as possible to the address we have on file for you. Get My Payment will be updated to reflect the date your payment will be mailed. Typically, once the payment is mailed, it will take up to 14 days to receive the payment, standard mailing time.
