Yes, you have HDHP coverage, but if you were covered under his plan, then see this -
When going through the questions, you will get to a screen entitled "What type of High Deductible Health Plan did [spouse (you)] have on December 1st 2016?" (see screenshot below).
If your spouse (you) was covered under your health insurance plan, then you should select "none" not "family or self-only." You are selecting none because your spouse (you) does not have their own coverage, they are covered under your (his) plan. If you select one of the other options, then you will get a notification about a coverage lapse.
