How can I change bank information with irs

Once you have submitted your return, you cannot change any banking information on your return. If the account number or routing number is incorrect, the IRS will mail you a paper check in the mail.

You are referring to the IRS portal for updating your bank information for the Advance Child Tax Credit being distributed by the IRS in the months of July thru December 2021.
