Nonresident Wisconsin Return

Hello, I am working on a nonresident Wisconsin return.  Wisconsin has pulled in the info from my Federal return about Capital Gains and Losses.   On the Capital Gains and Losses Worksheet in forms view, I see that there's an option to omit these transactions from being included on my Wisconsin return and indicate that it is not subject to Wisconsin tax.  How do I know if it should or should not be omitted?
