#1 Joe should NOT adjust the return until the IRS has made the changes in their system AND the program has also been updated so his return is not held up in processing for months. Chances are this will be a MARGINAL entry on the Schedule 1 line 7 which the program doesn't have yet and the IRS is not ready to accept yet. If Joe does what he plans to do he will be opening up a can of worms for sure. Not a good choice at all.
