You should get your 1095-A by mid-February, but only if you purchased health insurance in 2023 through Healthcare.gov or your state's Health Insurance Marketplace.
If you do not have health insurance through healthcare.gov or your state's marketplace, you can type 1095-a in the Search box, then click the link that says "Jump to 1095-a." That should take you back to the screen that asks whether you received a 1095-A, and you can answer No.
TurboTax may think someone had Marketplace insurance. You can review the questions pertaining to coverage by returning to the Health Insurance section and follow these instructions, if you did not have Marketplace or a 1095-A.
Turbo Tax will walk you through the questions for health insurance.
