Box 16 and 17 W2 issue

Hello,  I know this has been previously asked but I wasn't clear on all the steps to solve this.  Please HELP!

I live and work in NJ only.  Have 2 W-2s that have NJ in box 15, blank Employer State ID, blank in box 16, and FLI amount in box 17.  I then have another row of these with state wages and state income tax withheld.  When this loads into Turbo Tax, the program tells me that box 16 can't be blank. If I enter the same state wages as in the other row of box 16, won't it double my NJ income?  I read that FLI (for NJ) should be entered in box 14, even if it's listed by employer in box 17. HOWEVER, do I then just remove this row all together and only leave stage wages and income tax withheld?  OR should I just enter $0 in box 16 corresponding to FLI?  I found that when I do either of these options my NJ tax refund increases SIGNIFICANTLY, which makes me worry that it's wrong.  HOWEVER, if I LEAVE  and add wages to both rows (i.e. by State wages and by FLI), I noticed my state wages were DOUBLED by Turbo Tax on Form NJ 2450 (it's not common to have this form but I do as it seems I overpaid the UI/WF/SWF).  In any case, I am VERY concerned.  I was one click away from filing...  PLEASE HELP.  I am sure I am not the only one puzzled by this.  THANK YOU!
