Per the IRS Get My Payment FAQ:
What if I don’t recognize the bank information shown?
Some recipients may have had their payment directed to the temporary bank account established when their 2019 tax return was filed. The IRS and tax industry partners are taking steps to redirect stimulus payments to the correct account for those affected. The IRS anticipates many additional taxpayers will receive payments following this effort.
If you don’t get a payment and you’re eligible to receive one, you can claim the Recovery Rebate Credit on your 2020 tax return. Please see What is the Recovery Rebate Tax Credit? for more information.
