Head of Household vs Single

[CT6451]

Why can't I file as head of household vs single? I've filed head of household for years, but now turbotax will not allow me to select head of household.

Do you have a qualifying child or Dependent? 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.
