Schedule K1 form 1065 section 13 has the code W* i don't know what the star is, there's no description anywhere. It's 0 anyway. Do i need to find it?

it says *see attached statement for additional information. Not sure if it has to do with W. looked at other documents. not sure what to look for or where. also it's 0 again, do i have to specify what 0 is
