@henrymatw , 

How long did it take for the acknowledgement to finally change for you?  

This is my first NJ tax filing, so I don't know what's normal for them, and, of course, I recognize not much of anything is actually operating normally right now, but the 3 returns were all eFiled over 24 hours ago and the Federal and Virginia returns were both accepted by their respective taxing agencies within a couple hours, but the New Jersey return status remains, "Return Sent to the State."
