If I am a self-employed consultant in OK to previous employer in CA, do i list all self-employment income on CA tax return as "from a CA source while a non-resident"?

"self-employment income from California sources while non-resident of California." 

I moved from California to OK in August 2017. I worked as a self-employed consultant in OK providing services to my previous employer in CA. I received a 1099-Misc from them with my income listed in box 7, nonemployee compensation. Do i need to list all my self-employment income on my CA tax return as "from a CA source", or since my consulting business and residence is in OK, do i answer this question with a zero? Thank you for your help.
