Medical Expenses

I was on Obama Healthcare for half of the year and then on my own health insurance for the rest of the year.  However, when I go to enter my Medical Expenses in Turbotax, it states "NOT" to include the premiums I had to pay out of my pocket for the first half of the year that I was on Obama Healthcare??

 

Why would I not include my premiums since the Obama Healthcare premiums/credits which was sent to my Providence Healthcare Insurance was not enough to cover my Providence insurance Premiums and I was billed each month from Providence Health Insurance to make up the difference?

 

I would expect to be able and write these premiums I paid out of pocket on my medical expenses???
