If you qualify as Head of Household, when you enter your filing status (single or married filing separately) into MyInfo, and then enter your qualifying dependent, TurboTax will offer HOH as your filing status.

In short, not all dependents are qualifying persons for HOH.  If you believe your dependent should be a qualifying person, double-check the relationship you assigned them when you entered them in the interview.
