Schirallicpa - I think that is what happened with one of my clients too where wife died in April 2019. He says he always makes a partial, rounded deposit of checks he receives, and he deposited $2,000 right around the end of April 2020 when he would have received EIP#1, and then didn't get the EIP#2 at all.
I filed his return with him getting his full $1,200 for EIP#1, -0- for EIP#2, and claimed the RRC for the $600. No way to even include anything for the wife now since he is now filing as single, not MFJ.
