Retirement tax questions

Thanks a lot for your help.

Yes, I don't have any CA source income, neither a home nor a vote.  However, 3 years ago (summer 2021), I visited my brother in CA for 3 weeks vacation, and since I wanted to rent a car, I applied for CA driver license and got it.  Is this an issue?  My vacation in CA was for only 3 weeks during the last 20 years.

Thanks and appreciate your help again
