Are they sure the IRS didn't issue the EIP? I had one client who swore they did not get it, but the IRS "Get My Payment" said they did (probably tossed it).  They eventually were able to call and request a lost EIP card and request a replacement.  It took about 1 week to get the replacement.  I can now complete the return without the RRC and without the client having to request a trace which I am sure would have delayed the return and refund.

I was checking "Get My Payment" for all my clients who weren't sure if they received it, but it has now been disabled for EIP1 and EIP2.    Clients now have to create an account where they can access when they received EIP1 and/or EIP2 and the amounts they received.  More work on the front end, but I am sure it will save some on the back end.
