Why the FTB 3800 is need when I have unearned income that is NOT sourced from CA?

I am a college student who did internship in CA in 2025 for 12 weeks. I am NOT a CA resident, and my unearned income is NOT sourced from CA. I am preparing my 2025 return. For some reason, the FTB 3800 form keeps popping up. It also asked for my parent's 540 NR info. My parents are Non Resident of CA as well but my Dad may have some taxable income. He would have to file an extension for all his returns this year. I did some research and it looks like I really don't need to fill 3800 since non of those income is taxable for CA. Anyone can help me?
