I have almost the same question.  I have code Z with STMT after it.  I don't see a statement A as was suggested in other topics related to this.  I have what looks like a 199A information, box 20 , code Z.

On the very last page there is a section 199A -Unadjusted basis of assets with a number 2,263.  Anyone know how I am to fill out the K-1 information??
