If you had health insurance in 2018 you would have received a Form 1095-A, 1095-B or a 1095-C.
Forms 1095-B and 1095-C are not reported on a tax return. If you obtained health insurance through one of the state marketplace exchanges or through healthcare.gov you would have received a Form 1095-A.
Form 1095-A is reported on a tax return. You were asked specifically in the Health Insurance section of the TurboTax program if you had this type of insurance and received a Form 1095-A. The 2018 tax return cannot be completed and filed without the user of the software completing the Health Insurance section.
