On the part year resident NJ form, how should I calculate the payment attributable to my NJ resident period? Should I allocate the NJ tax withheld based on when I moved?

When calculating the tax payment allocation, Turbotax recommended I edit my taxes paid and allocate them differently between the NJ resident and NJ non-resident forms to end up with no refund and no balance due on my nonresident return. I want to ensure I'm calculating the NJ tax withheld during my resident period correctly.
