I paid $6,500.00 health care premium tax last year and want to apply this credit to my 2023 tax return. How do I do this?

Premiums you spent for health insurance are deductible as a medical expense if you itemize. You can only deduct a total amount of medical expenses greater than 7.5 percent of your AGI.

were you covered under marketplace insurance, aka Obamacare,  aka Affordable Care Act?  you need the 1095-A from the Marketplace which must be entered in your return. failure to report having this coverage will result in rejection of your return.
