This is a user to user forum. No one would know your bank account information. You can sign back into your return & you can look at the banking information you entered in the File section.
If you are asking because of the second stimulus check, then the IRS will use your information from your 2019 return. If you bank information is incorrect or the bank account is closed, the IRS will automatically switch you to receiving a check once the bank bounces back the deposit.
