Do I need to file for IL tax return 1040 and NR when I live in NJ? Work in Consulting and W2 box 16 has less than $10K in "State Wages"

I am in Consulting and traveled to IL for work in 2019 for a period of time. My 2019 W2 box 16, "State wages, tips, etc." shows less than $10K.

Box 17 "State Income Tax" shows a few hundred dollars. 

Do I still need to file separate tax return for IL?  Both IL-1040 and Schedule NR?

Thanks in advance.
