IRA withdrawal and state taxes

I took my first withdrawal this year from my Rollover IRA. I paid both Fed and CA taxes. I am currently living overseas for the past 2 years. I was told told that I did not have to pay state taxes to CA. Is this true? I was concerned because it is CA, state taxes are based on the state you earned the money invested in the IRA.

 

If it is true, how do I get my payment back?
