College Internship - Income from Another State

[HI96821]

Aloha, Our college student attend college in California and had a summer internship in California in 2023.  We reside in Hawaii and our son lists his state of residence as Hawaii according to Turbo Tax.  I am completing the tax return for our college student and listing his residence as Hawaii even though he attends college and held the internship in California.  Do we need to also complete a tax return for the State of California for the income earning over the 2023 summer?

Thank you
