It is correct if you are referring to this screen in the Minnesota section that mentions your spouses's 401-K contribution that was listed in box 12 on their W-2 form:

The reason that it is mentioned is that the amount was not reported as wage income on line 1 of Form W-2, so it is income that is not reported as taxable on the federal return. There is no association with this and your SEP-IRA contribution, as that does not represent income that is not being taxed on your federal tax return. It is a separately listed deduction from your federal taxable income that gets the same treatment in Minnesota, so it does not have to be adjusted on your Minnesota return.
