It depends.
As we cannot see your personal return, can you please provide us with a little more detail so we can assist you?
Are you referring to your state income tax return?
If so, please comment with the state and so we can assist you.
I haven't filed it. But I am eligible for this credit if I have lived in the state for a whole year correct? Background story: I am originally from a different state but I moved to WI for school. I have been paying rent in WI since December 2019 but I officially moved in January but in December I was working at my old job back home in another state. So i am putting I officially moved in January to WI, is that correct?
That would be correct. If you moved in January to Wisconsin, that would be when you officially moved there.
