I know the 1040X is not final yet but just like every year, 4 days after a client's return is transmitted, they call or stop by to drop of the W-2 "that they totally forgot they even worked there last year".  Anyway, just to keep the paper clutter down, I entered the W-2 info on their return to prepare the 1040X and the 1040X is not calculating that they are getting their Recovery Rebate since they did not receive a stimulus payment.  It doesn't include the rebate as part of the original payment and causes that amount to be added to the balance owed.  Just a heads up so this can be fixed or figure a work around.
