Not a lot of thoughts, but I can offer an observation.  It appears that the shiny new $300 deduction on the federal is causing problems with a number of states.  I have seen several posts about wonky, or should I use the official Intuit terminology of unexpected behavior, related to the deduction this year.  I don't know if Wisconsin is on the radar yet, but you might want to contact support at some point to make sure Intuit knows about the issue.
