Error on code Z simply requires Schedule A to be filled out at bottom of K1 entry screen.  That Schedule must not get filled out on importation.

I DO NOT SEE ANY SCHEDULE A UNDER K-1 WORKSHEET AFTER LINE 20 THERE ARE SECTION A B C D

If an amount is entered in line 20 scroll down until you get to section D1 be sure ordinary income (loss) is entered plus any other applicable fields and section D2 including the SSBT check box and you should be error free

Ashley is correct.  It is actually D1 on the K1 worksheet.  But you enter the numbers from the Schedule A there where it says Schedule A info. 

THANKS!
