I've had 2 separate clients now on PR 2.x find out during W2 processing that one or more employees had no withholding in all 2020.  I just logged into one client with an employee marked as MJ1 who grosses about 23K per year, paid weekly.  That should be around $20/check in Fed WH.  NOTHING is being withheld.  I flipped the Supplemental off and on, no changes.  Has anyone else had a client report this?  In all cases, it is the new W4 choice, not the old 2019 or older withholding selection.
