Why would my stimulus check have different last 4 numbers to deposit my check?

Are you saying that you are viewing your third stimulus payment information at the IRS Get My Payment tool?

You do not recognize the checking account information that is listed?  Please clarify.

This TurboTax Help states:

Do I need to do anything to get my stimulus check?

You don’t need to do anything to get your stimulus check. The IRS will determine eligibility based on your last tax return (either 2019 or 2020) and will likely send your payment to the bank account where your tax refund was deposited.

Are you seeing banking information that was reported on your 2019 Federal 1040 tax return?

If the IRS finds that this checking account is closed, will the IRS issue your third stimulus payment in the form of a check?  Is the 2019 tax information mailing address information still correct?

Will the IRS mail your third stimulus check?  We do not know.  Does the IRS even have a good mailing address from your 2019 tax return?  The IRS does not know.

We are waiting for more direction from the IRS about such a situation.
