How do I change too file head of household. it doesn't list it.?

Go to Federal Information Worksheet, and check Box 4 under Federal Filing Status.

If you are filing as Single or Married filing Separately as soon as you enter a qualifying child it will automatically switch you to Head of Household.

 

Go to My Info and look at filing status.
