Deductions & credits

So for instance, for the Question: Did you spend your HSA money on medical expense only, if "No, I didn't" is selected then 2 sub-category options appear: 1) I spent part of of it on medical expense OR 2) I didn't spend any of it on medical expenses.  IF the later is selected (#2 - I didn't spend any of it on medical expenses) AND the "Amount rolled over into another HSA or MSA" field is left blank. When continued is selected the refund increases by like $2K +, which I thought was weird.  I thought it would decrease the refund, but instead it increased.  So not sure if this is right or wrong
