You do not need to enter the 1095-B or the 1095-C into TurboTax, just the 1095-A. Just put the 1095-B into your tax folder and forget it.
The old Health tab has been relocated to the Medical section under Deductions and Credits. But if you have a 1095-B, you no longer need to indicate that you have health coverage on the federal return (California and Massachusetts may require an entry in the state interview, however).
