Texas is my primary residence. I lived in NYC from 1/1/20 to 4/6/20, and Texas from 4/7/20 until now. I purchased my home in Texas. Texas has no state income tax return. I went through the entire process and for obvious reasons itemized my deductions on my federal return. When I did my state return for NY I thought it would ask me about deductions but it automatically itemized them from the federal return. I noticed the resulting tax amount for NY looked off and when I was ready to file reviewed the forms and saw that, in the NY state deductions, it itemized them and placed mortgage interest and property taxes on them. I haven't found a way to change that.
