RSU double taxation by NY after moving to CA

Hi,  I am doing my daughter's taxes.  She works for a company not based in either  CA or NY.  In Feb of 2023, she moved from NY back to CA.  She had some RSUs that were (acquired and disposed of) both AFTER she left NY.  However, in doing her taxes and reviewing her W-2s, She seems to be taxed by the State of NY almost as if she was the a resident for the whole year.  Eventhough, during the TurboTax initial steps, we did specify the dual state status with dates, but the NY taxes calculated by the software are staggering (2.5 times what is on W2).  Can anyone shed some light on this please?  Thanks.
