Joint tax return while living in different states

My spouse and I got married last year and we are planning on filing a joint tax return for 2024.

 

I live in Michigan and lived in Michigan entire 2024

My spouse lives in New York and lived in New York entire 2024

 

I am not employed and was not employed entire 2024. However, I have Consolidated form 1099, from stock sales.

My wife is self employed and was so entire 2024, in NY. 

I understand that we just file a joint tax return for federal.

Michigan states: "If you filed a joint federal tax return, you must file a joint Michigan income tax return". 

New York states: "If one of you was a New York State resident and the other was a nonresident or part-year resident, you must each file a separate New York return. The resident must use Form IT-201 and non-resident IT-203." - We also have an option to file a joint NY tax return. 

How can we file married jointly?
What is the step-by-step process?
How many returns are we going to end up filing in total?

Thanks in advance
