Free State Download?

I live in a state that does not require me to file state taxes.  I'm helping my in-laws with their taxes and they lived in CA for 2 months last year.  Since I purchased TurboTax Federal only, is there a free state I can download to file their taxes?  They sold their home in CA so I'm not sure if I can use the "simple" online filing for State.

 

Thanks!
