This client insists that he did not receive Stimulus #3 for $1,400.  Yet he did receive Letter 6475 affirming that he was issued the Economic Impact Payment of $1,400.   Further, the Lacerte program does not allow for claiming it on the tax return via line 30 of the 1040, indicating that there must have already been a match-up to the SS#.  Is there any way to trace when & how the stimulus was paid--whether by check or by direct deposit (and, if so, to what checking account)?  So as to prove to the client that he actually DID receive the payment?
