Check your copy of Form 1095-A. If your Health Insurance is only for you, that is assumed in Part I of the form (Recipient Info), and no entry is needed in Part II.
Enter your 1095-A as it is reported to you. If you need to go back and Edit your entry, type '1095-A' in the Search area, then click on 'Jump to 1095-a'.
Here's more info on Form 1095-A.
