Just because there is a line on the ProSeries Schedule C entry sheet for health insurance, doesn't mean that it gets deducted there.  That entry goes to the SEHI worksheet, where you may or may not get an adjustment to income (depends on whether you have a Schedule C profit).  Given the choice between making it logical and making it confusing, Intuit programmers (who go to H&R Block for their return preparation) usually choose the latter.
