If you have already submitted your tax return, then wait until the IRS either accepts or rejects your return.
If the IRS rejects your return, you can sign in to your account and make the correction to your bank information before e-filing your tax return again.
If the IRS accepts your tax return and is unable to direct deposit your refund, then the IRS will mail your refund check to the address listed on your tax return. There's no way to change your bank information once the IRS has accepted your e-filed tax return. You can check the status of your refund by using the IRS's Where's My Refund? tool.
