How can I force Turbotax to accept my Head of Household status based on a non-dependent qualifying person?

Grandson and daughter lived with me all year. I'm not claiming GS as a dependent. If I choose that daughter lived w/ me and contributed to GS support, it rejects HOH.  But if I say she didn't contribute, it makes him my dependent.  Can't he be a qualifying person, but not my dependent? How do I make Turbotax accept this?
