Ahh...so on a W-2 ? and NJ SDI too...yep, it always helps to define what form you are talking about...so we don't waste time going down the wrong path.....none of us can see your forms .
Like I said though.....NJ forms say DO NOT FILE because they aren't ready in the software, and won't be for about another two weeks.

It's possible that the MAX values for that NJ SDI have been changed for 2020 (Yep, I just checked...they upped it for 2020).....but the Max values probably have not been updated yet in the software yet...since the NJ forms, and their associated calculations, Are Not Final yet in the actual software. Thus, when they do get finalized 2 weeks from now, that error may go away after that (IF you made sure the values are correct in the software).
( DI and SDI should be the same thing...unless the employer is doing something strange )

Don't mail the Fed ! ...wait until mid-February and e-file it instead. You may be able to e-file the NJ tax returns at that time too.
The coronavirus ahs messed up things so badly, that IRS may still be working on some 2019 mail-filed tax returns, and may not get to yours for another 4-8 MONTHS if you mail it.
