1099 Income for California nonresident - Physician working out of NJ

There appears to be very confusing and incorrect answers for this question.  For a physician who is licensed in California and seeing patients in California from NJ - is there a requirement for filing taxes in California?

Situation - NJ resident - working and living in NJ.  Has never stepped foot inside California.  Receiving multiple 1099-misc and 1099-nec from California and non-california based businesses such as national telemedicine companies.  Patients seen are split between California and NJ.  According to California FTB - must file taxes in California because patients and benefit is seen in california.

There are posts here saying the income is NJ sourced and no need to file California taxes.  Please help and clear up the confusion.
