Get your taxes done using TurboTax

Form 5121 does not appear to be working in the MI state return for 2020. When entering 225 days paid and 24 days worked in Detroit, it is calculating that 0.38% of the wages are taxable by Detroit. It should calculate that 10.7% of the wages are taxable by Detroit. Is there a reason behind this difference or is there a calculation error on the form?
