I enrolled in an HSA in August of 2017. Only coverage prior was VA. How do I answer what type of HDHP did I have in 2017? Self only every month of the year?

My confusion is that it states that I had to have an HDHP before having an HSA. This is the reason I selected that I had an HDHP during at least one month of the year. Selecting I did not have coverage seems more logical. Thank you for any clarification provided.
