Military Spouse and State Taxes

So I see a lot of people asking the same question but I have no clarity on how to file. I am a military spouse of an active duty servicemember, both of our home of records is AL. We are stationed in CA on orders. I have made W2 income in CA, but my taxes were not withheld, so I know I owe. What questions do I answer on our joint return in order to pay AL taxes for the CA income I have earned?
