Double Tax on RSU income in year 2 after moving from CA to NY

Here is my situation:

 

I moved from CA to NY in June 2019. On my 2020 W2 I have RSU income attributed to CA and NY since I worked in CA while the RSUs vested in 2019. 100% of the RSU income is taxed by NY while a percentage of the RSU income is taxed by CA. This means that the RSU income taxed by CA is also being taxed by NY. 

 

When filing out my taxes I am a full year resident of NY and do not see an option to attribute a portion of that RSU income to my time in CA. What is the correct way to complete my taxes this year?

 

Thanks in advance!
