State tax filing

Does it also apply to Insurance Premiums taken from my paycheck via Cafeteria plan?
The premiums were not taxed by Federal gov., but they were taxed by State of NJ, so on W-2 they are part of NJ wages.
If this is correct and Health Insurance Premiums can be deducted as medical expenses, then all these years I was losing few hundred dollars of tax refunds...
I asked couple of my friends, and they also did not know they could deduct health insurance premiums.
One would expect TurboTax at least would notice that I paid insurance, but the field for it shows zero and I would get some warning... no prompt, nothing?!
Sure, there is a box on medical expenses screen, but it is not clear where to get those numbers, b/c it is not on W-2 as a separate amount, and it needs user to calculate it, so you need to know "how"... and most important – "you really can do it".
I think this is a big flaw in the NJ tax preparations in TurboTax application design!
Why do I need TurboTax if I need to hire a tax adviser to double-check my return…?
