Hi - Indicate that you had insurance all year, and answer no to the question "Was anyone covered by any of these plans in 2016?". That's it!
There is no credit for having insurance. You could get a deduction if you spent more than 10% of your income on medical expenses (it's 10% for most people), but it's hard to get because most people don't spend that much. Enter your medical expenses in that section of deductions and credits.
Hope this helps!
