The problem I encountered when filing jointly was that I logged into my IRS account and used the EIP1 and EIP2 amounts listed there. This did not show the EIP1 & 2 payments for my wife so I took a larger credit than I should have. When the IRS sent me a revision on the return I went back and checked what I actually received and was able to see where I went wrong. Interestingly, when I login in to my IRA account the just received EIP3 payment shows the total payment for both my wife and me.
