HSA

I am still employed and my wife is retired. We are both covered by my employer's HDHP. I have an HSA. My wife, who is over 65, has Medicare part A only. After entering my HSA info, Turbotax Deluxe asks about my wife's HDHP coverage which I enter as family. But the next question seems to indicate that Tubotax sees a lapse in my wife's HDHP coverage. What's going on?
