how to find LCA of Wisconsin?

I know there is a site called FLCA data center .com. I went to the site but there its asking for too many details which I I don’t have. I don’t know if I will be filed under level 1 or level 2 or whether the occupation which I have to select from the list has to be the same as what is in my i797 or what is in my offer letter.

Is the LCA for all of Wisconsin the same or does it change based on cities within it?
