I have a partnership K-1 with the following reference "Schedule K-1, Line 13, Code ZZ."

A brief description: "Pass-Through Entity Tax - NY; reduces Line 1, Ordinary Income $2,677"

Questions: 

1)  Why would it state "reduces Line 1, ordinary income?"

2)  I do not believe there is any line on the federal K-1 for this item?  

Any ideas would be appreciated!

Thank you!
