In order for the Qualified Business Income Deduction (QBI) to be calculated, the K-1 Form must contain certain codes pertaining to "qualified business income".
The "qualified" income for the QBI deduction is reported on your K-1 in Box 20 code "Z to AD" for Section 199A income if it is related to a Form 1065 (Partnership).
If related to a Form 1120-S (S-Corp), it will be reported in Box 17 code "V,W,X,Y and/or Z".
After you have entered all of the information from your K-1, you will need to answer a couple of questions regarding the nature of the income and your expected income. If you meet the qualifications, the QBI deduction calculates after that.
Please comment if you need additional clarification.
