That is for a Form 1095-A which you would have received if you had health insurance through one of the state Marketplace Exchanges. If you did not receive a Form 1095-A and did not have health insurance through the Marketplace then you do not complete a Form 1095-A.
Forms 1095-B and 1095-C are not entered on a tax return. You would just keep of copy of those with your records.
Delete the Form 1095-A you started to enter if not needed.
Enter 1095-a in the Search box located in the upper right of the program screen. Click on Jump to 1095-a
Delete the Form 1095-A listed.
