Dependent child required to file taxes in California?

My 18 year old dependent son is a student full time and working a part time job.  He made about $9,000 last year.

 

I started to do his taxes in Turbo Tax desktop version and it shows he should get about $260 back from the federal and $1 back from the state of California, where we both reside.

 

I will file his federal return since Turbo Tax provides free e-filing.  But do I need to file his California tax return ?  The filing fee online is $25 using Turbo Tax or if I print and mail it seems like a bit of a hassle.  

 

I'd like to just e-file the Federal and not file the state at all, is that possible?
