If you paid for your insurance through a health insurance marketplace (Ex. Covered California) then you will enter your 1095-A information and there will be a place to check that you are self-employed. It will automatically put the information in the right place so you would not need to put it on Schedule C. That is my understanding, but I am a customer, not an employee of Turbo Tax. Just be careful not to count the insurance premiums twice. If you had other insurance available to you, such as on a spouse's plan, but chose not to use them then you may not be able to count your payments.
