Form 1095-A is not included in the TurboTax free edition. Form 1095-A, is used to complete Form 8962 Premium Tax Credit, which is not supported by the free edition.
I think TT deveopers did not do a good job of implementing the health care penalty change in their program. Because it's no longer a requirement to have health insurance, the program isn't prompting the user as it did in prior years to review this subject. You can find it under Deductions and Credits section/Medical. It's no longer a separate section making it easily missed.
Users of the free product should have been better coached by the software in this area.
