W2 without benefits, healthcare premium deduction

I work per-diem for a company which issues me a W2.  They do not offer any benefits or healthcare insurance so I pay for it out-of-pocket with post-tax dollars off the exchange as I do not qualify for any subsidy. I have no outside income aside from a rental house. Thus I am essentially “Self employed” but do not have a business. Can I still deduct health-insurance premium and healthcare expenses similar to if I had 1099 income (which I do not).  If so, what seciton of turbo-tax would I do this in (wages & income or deductions and credits).
