@miller4mi -- Here is the complication in your situation: California and Arizona are "reverse-credit" states. That means that your non-resident state of CA will give you a credit for the taxes paid to AZ on the portion of your income taxed by both. ("Reverse-credit" because normally it's the home state that gives the credit.)
Therefore you should complete your home state AZ return before you do your non-resident CA return.
CA currently has reverse credit with Arizona (AZ), Guam (GU), Oregon (OR), and Virginia (VA).
See "California Nonresidents" in this reference:
