New client's W-2 Box 1  says 10000. As is box 3 and 5. Nothing on W-2 is coded as health insurance.

She states that her medical insurance is not pre tax. Brought end of year check stub showing that indeed  Medical 2000 and salary 8000 for a total of 10000.  This is an example not the actual amounts. 

I am asking for an opinion from the group. Is the check stub enough info to take the amount of insurance as an itemized deduction? I have tried calling the company but only getting a run around.
