In January of 2022, I relocated from NY to CA. So, for the first paycheck (for base salary) I get in January, I have state tax withhold from both NY and CA; and all future paychecks only have CA withholding. But due to trailing RSU liabilities, the RSU was granted when I was in NY and vested when I was in CA has state tax withholding from both NY and CA. So I am wondering, in this case, should I report NY non-resident tax first and then claim a tax credit on my CA return on the income from my 2022 first paycheck and RSU with both NY and CA withholding?
The second question is, I purchased a home in CA in 2022. The interested I paid in 2022 was about 40k. When I file NY state non-resident return, Turbotax calculated the deduction for this home mortgage interest is around 20K; when I file CA state return, Turbotax also calculated a deduction for the mortgage interest around 20K. So, I am wondering, can I claim tax deduction for the mortgage interest for both CA and NY state return?
