Medical Co-Payment Dedection / Credit, NJ and Federal ?

Hi,

 

Do I have this correct?

 

I paid $3900 over 12 months in bi-weekly deductions from my check for health insurance.  My employer paid the rest of the premium.

 

So, I see block 1 on my W2 is 3900 less than block 18.  I assume that's the extent of how you get the credit deduction federally?

 

And I assume being a gross income state, you get nothing back for the 3900 from NJ?

 

Thank you!
