The Health Insurance tab has been removed because the penalty for not having health care insurance for tax year 2019 and beyond has been removed. 

If health insurance was provided from the Marketplace, state or healthcare.gov then a Form 1095-A would be received.  The 1095-A is required to be entered so that the Form 8962 Premium Tax Credit can be generated.

The 1095-A information is entered under Deductions & Credits this year:
