Thank you for the response.
Looking at this again, it appears the “Your Minnesota Bottom Line” webpage isn’t properly displaying the prorated tax liability as I'd expect for the taxable income line.
I had expected the line for "Minnesota Taxable Income" to show an amount similar to the amount from W2 box 16 less the deductions, but it shows a much larger amount (4.7x) as taxable vs. the amount in my W2 box 16.
The amount that is showing I owe for "Minnesota Income Tax" line calculates to 3.9% of my W2 box 16 though, so that seems much closer to the expectation.
