For HOH filing status, if you're not taking the qualifying relative as an exemption, how do you enter that into Turbo Tax?

I'm looking for the mechanics of how you actually enter this into Turbo Tax.  If the qualifying relative is a dependent which he is, HOH is fine and I get the exemption.  I don't want the extra exemption.  What do I need to do to not get the exemption for the qualifying relative while still maintaining my HOH status?
