K-1 Box 13 Code W - Various Entries

[Curious One]

I have various descriptions for Code W:

- Cash Contributions

- Interest Expense

- Asset Management

- All Other Deductions from Pass-Through

- Other 2% Floor

First question:  Is there any rule on which should be entered as positive or negative?

Second question:  If these items don't impact the income / loss generated by partnership activity, where on the return would/should they appear and do I have to enter them there manually?

Third question:  If they don't appear elsewhere, what is the point in providing the information to me?
