NJ fiscal year corps and S corps always arrive late. I just clicked on Update 2018 software and there were LOTS OF UPDATES.
BUT NO NJ FISCAL RETURNS YET AS OF JANUARY 10, 2020. This is far too late.
In the software, WHEN IT COMES, it is listed as another state return to be used. In 2017, THE LAST YEAR THE NJ FISCAL IS AVAILABLE, the states listed are NJ 17 corporation and NJ 18 corporation.
So for 2018, you are looking for NJ 18 corporation and NJ 19 corporation.
