How do I get a 1099-HC form?

I used the secure message option on the main website, the person who responded told me I don't need that form and probably mean the 1095-C but then said I don't need that either so they offered me nothing.

I called customer service twice today and was hung up on both times.

One of my dependents goes to school and works in MA, they need the 1099-HC form in order to file their state taxes.

How do I get this form?
