In some cases, the IRS has received a 2020 tax return, but hasn’t yet processed it. In these cases, stimulus payments may be issued to the account on the 2019 tax return.
If the bank information is invalid or the account has been closed, the bank will return the payment to the IRS and the IRS will mail it to the taxpayer by check at the address they have on file.
Please see the TurboTax Help article How will the third stimulus impact me? for more information.
