Can I deduct Health Insurance Premiums I pay for SAG-AFTRA Health Plan?

I have an S-Corporation, which is a Signatory Producer with SAG-AFTRA.  This allows the S-corp to book SAG-AFTRA session work, paying its session vocalists who are affiliated with SAG-AFTRA wages based on SAG-AFTRA scale.  I am President and the sole Shareholder of my S-corp, and I'm also a SAG-AFTRA performer.  So my S-corp "loans me out" to production companies, who pay the S-corp. for my vocal services.  My S-corp in turn pays me (W-2 wages as an employee of my S-corp) for those sessions.  My S-corp also pays Health & Retirement contributions to the SAG-AFTRA Health & AFTRA Retirement Plans, the percentages of which is calculated based on the earnings I made for a given session.  If I, as a performing member of SAG-AFTRA, make enough "qualified earnings" on these SAG-AFTRA sessions in a given 12-month earnings cycle, I become eligible for participation in the SAG-AFTRA Health plan.  When I have qualified, at that point I am enrolled in 12 months of the SAG-AFTRA health plan, which then requires me to pay quarterly insurance premiums for the health coverage. SAG-AFTRA states the health play is "a self-funded ERISA plan and therefore not subject to state-mandated insurance laws."  I also have a Schedule C sole-proprietorship business.  My question is, may I deduct the quarterly health insurance premium payments I make as a self-employed  person, or even somewhere else on the Form 1040. since I have some schedule C income as well?
