If you purchased health care insurance through one of the state Marketplace Exchanges in 2019 then you should have received a Form 1095-A. Go to this healthcare.gov website - https://www.healthcare.gov/tax-form-1095/
If you purchased your health insurance through the Federal or State exchanges, you should have gotten a 1095 A. It shows what, if any, part of your health care premium was subsidized. If you purchased private insurance without any subsidy from the Affordable Care Act (Obamacare), you probably didn't receive one.
