I had Catastrophic coverage from Marketplace for 4 months this year while self-employed. Is this deductible from my 1099? Since it was catastrophic it's not on my 1095-A.

The internet at large seems to say it is deductible, if you had no other options, but the Health Insurance Premiums expense section of Turbotax says not to enter anything that was purchased from the marketplace. So I'm unsure.
