Health Insurance Marketplace Premiums

I retired early and have been living on savings before taking SS or IRA withdrawals, so my income is minimal. After COBRA ended, I was directed toward Medicaid because of my income. I declined Medicaid and signed up with the Health Insurance Marketplace but declined premium credits because I have assets. Entering the 1095-A in TurboTax shows that I would receive a huge premium credit, but I plan to not use this or file the Form 8962. Could I still claim the premium payments as deductible medical expenses? Any other advice? I'm trying not to take advantage of a program for people who really need help, but I don't want to miss a legitimate deduction.
