W2 has CA taxes for entire year instead of split between two states

California based company

 

We lived in CA until Jun 30 then moved to SC. Despite our continued efforts to get the address changed and the taxes corrected, they never did. So for the entire year we paid CA taxes. I have entered the W2 as received from the company but have no hope at this point to get it corrected. How should I go about dealing with the discrepancy in state income and taxes?
