Hi jfindley

Sorry have not checked in for quite some time.  Much to my chagrin, the client that I was working with on to address the recovery rebate credit issue turned out to be simple yet frustrating.  After much back and forth with the IRS, we learned that my client did indeed receive the additional Economic Impact/Stimulus  Payments.  The client provided me with the incorrect amounts they received and also failed to provide me with a payment.

The return was wrong because of this. 

Looks like I found the smoking gun. 

Sorry I wish I could be of more assistance on this.
