health savings accont

I have an allotment to an account that was not properly set up as an HSA. Moreover, I did not have an HDHP anyway. SO, I have the allotment on my W2 and not sure how to handle it in the software.  My attempts thus far have yielded a tax benefit for which I'm not qualified.  I believe I should pay taxes on the full amount because the medical expenses are not high enough to itemize, ie the standard deduction is better.  Need assistance with working through this, please.
