Capital Gain -Multi State

Request inputs on below

I have been a resident of Illinois for the past three years. I was renting an apartment. In May 2024 I moved to Michigan and working remotely for a job in Illinois. I still have a rented storage in IL. In 2024 my total stay in Michigan will be more than 180 days . In 2025 I might have to move back to Illinois state.

I have question on how state tax will be deducted

If I sell stocks lets say in Nov 2024 while I am staying in Michigan then do I need to pay tax state tax on stock gain to only Michigan or to both states ? Can tax softwares like turbo tax can differentiate which state should tax stock gains ?
Same question for Interest earn on Bank interest .
Does it matter for which state I am holding driving license ? For example if I am residing in Michigan but still holding driving license of Illinois .I will be considered resident of Michigan or Illinois
