I moved from CA to NY in 2019 and continued to work for the same company. My company did not withheld CA taxes the following years ( 2020 onwards ) when the RSUs vested, they only withheld NYS and NYC taxes. I recently only found out I have the pay taxes based on the grant date location as well, meaning I had to file CA tax return. I did not file CA tax return for the years 2020, 2021 and 2022.
I need advice on what I should do now. Do I need to file the CA returns and amend NY returns for the years 2020, 2021 and 2022? If yes, will the taxes I pay to CA get credited in the amended NY return when using turbotax?
