Do not enter the NJ FLI line as a box 17 in entry instead enter it in box 14 in TurboTax and select the NJ FLI item category there. The amount is informational so you know what you contributed and if the total exceeded the NJ limit you get a refund of the excess paid in.
The NJ max FLI contribution is $94.08. Here is a link with more information on NJ DES contributions.
