There is currently a bug in the step-by-step entry of HDHP coverage. If you indicate in step-by-step mode that you had differing coverage throughout the year, TurboTax incorrectly marks a box that is intended to indicate that you had no coverage at any time during the year rather than leaving that box blank. At present, a proper entry can only be made using forms mode of the desktop version of TurboTax so as to avoid the inappropriate marking of the box that indicates no coverage at any time during the year.
