I'm preparing an individual return. Can you explain the purpose of the PTO input at the following?
Go to Input Return > Income > Passthrough K-1's > S-Corp Info
Go to State & Local tab
Scroll down to Illinois Shareholder Share of Business Income (Loss) (EF only) {IL}

The input boxes correspond exactly with the same info on the Illinois state K-1. It looks like this should give PTO the information needed to allocate the income to Illinois, but I can't see where the input has any impact on the 1041. I can force the numbers I want but would like to know if this input is useful or necessary.
