Get your taxes done using TurboTax

When entering your personal information you should select Single.

When entering your granddaughter's information for Who Do You Support, select Another person and then select Grandchild.  For the number of months she lived with you select the Whole Year.  Select that she was Not Married.  When asked if she paid for more than one-half of her own expenses you should have selected NO.  And select NO for another relative supporting her.  Also, make sure that you did NOT check the box that her Social Security number was not valid for employment.

If you answered these questions correctly the program would have given you Head of Household filing status and asked a few more questions to verify your HOH status.

 

Go back through the entries for your granddaughter and make sure you answered all the questions correctly.  If the program still does not give you HOH status delete her as your dependent and re-enter.
