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

Are you Single or  Married filing Separately?  You need to enter a qualifying dependent to select Head of Household.  If you entered a dependent it would have automatically switched you to Head of Household if you qualify. Go back to My Info and check all your answers for your dependent.

Do you qualify for Head of Household?
