K-1 amounts in Box 17 with codes in the range of V to Z (for 1120S form) or Box 20 with codes in the rage of Z to AD (for 1065 form) are what are used to calculate the QBI deduction (Section 199A deduction). If you do not have amounts in the above box with the above code ranges, then the QBI deduction will not calculate for the K-1 income. Also, you need to completely enter the K-1 form before the QBI deduction will trigger, meaning you need to get through the entire section in TurboTax.
