Montana Non-Resident taxable income is overstated.

I had 3 sources of income in 2022, however, only a small portion of that income was taxable in Montana (I live in Idaho). TurboTax asked me what portion of my income was Montana taxable and I answered with the portion that is Montana taxable, however, after completing the remaining questions, TurboTax is showing that ALL of my income is Montana taxable. What am I missing?

This is the actual Montana form- you will see they use the total income but apply the Montana source income ratio to the total tax.
