You do not enter a 1095-B. The 1095-B is only showing that you had insurance. This form is no longer needed in completing your taxes. Many medical insurance providers still send these out. Just keep it with your tax papers.
The 1095-A is the only form that has reportable information. Answer the question that you do not have a 1095-A. This form is issued to those who have obtained insurance through the Marketplace and many of them receive a subsidy payment for their insurance.
