Thanks, but that does not explain why TurboTax skipped all of this. I did the step-by-step walk-through of the entire return. At the beginning of the "medical" section, it says:
What if I got insurance through Healthcare.gov or a state Marketplace?
If you signed up for a health insurance plan through Healthcare.gov or your state Marketplace or exchange, do not enter the premium amounts you paid in this section. We'll get the details on those plan premiums in the Health Insurance section.
Except... there is no such section. Look at the entire list of sections on the Deductions & Credits page. There's only Medical. The medical section subheading says, "HSA, MSA contributions, prescriptions, medical bills." I had none of those, so of course I selected no for medical expenses.
Proceeding through the return, there was no "health insurance" section or questions. This is a major defect that sets users up to have their returns rejected and, I would imagine, penalties for not paying back subsidies in a timely manner.
