If the taxpayer was issued a debit card for the EIP 1 or 2, but did not receive it, and you used the RRC on the 2020 return to get it, the IRS is disallowing the credit, sending a correction notice, and issuing the refund without the RRC.

IRS told me today, the taxpayer must call Metabank @ 800-240-8100 (Customer Service) to report the card lost or stolen. The old card will be deactivated and a new one issued and sent to the taxpayer.

eipcard.com is the web address for more information and options. 

Maybe I missed it entirely, but I do not recall this info being available on the IRS stimulus portal, before they took it down to process the 3rd EIP. It would have saved me a lot of time and phone calls.
