NEVERMIND:  I found somewhere you could right click to LOCK return.  I right clicked and saw I could "remove REP lock" and did; this fixed the issue.  I would like to know how REP lock got added.  I didn't even know you could right click and take actions.

ORIGINAL REPLY:  My reply is a month down the road; issue still exists, but not for all of my clients.  I receive this message:  "Client return cannot be locked because client is locked for REP processing" but it's been REPd and I've eFiled the returns (FED, AZ, CA, CO) and they've all been accepted.

I've closed and restarted program; I've updated MY ACCOUNT online for eFile status; I cannot lock this most recent client.
