Moved from FL to WI

I moved from FL to WI mid-year in 2024. I started working on my taxes and I am owing a lot in state taxes for WI. It's my understanding that I will need to complete the Form 1NPR as a part-time resident in the state of WI. I just wanted to confirm that's the case though I moved from a state that had no state tax previously (FL). Will filing this form lessen my tax burden to WI? I was super on top of changing my state tax withholding with my employer as soon as I moved to avoid any issues come tax time, but I am wondering if maybe I am showing I am owing so much in WI because it is taking into consideration my wages made throughout the entire year, rather than when I was living and working in WI? Advice would be greatly appreciated!
