TT is asking for "QBI At Risk Op Loss" Where on k1 is this information?

[bradsliz]

 I split my k1 (filled out everything except box 2. then did a different k1 with only box 2). But now in my review of taxes, TT is saying "QBI At Risk Op Loss" must be entered. No where on the k1/statement/k3 does it say this phrase.  Is this called anything else? 

Is it any of the figures in box 20 code z statement:

ORDINARY INCOME (LOSS) 
W-2 WAGES 
UNADJUSTED BASIS OF ASSETS

Thank you for any help!
