How do I claim the QBI deduction for a partnership K-1

[JulieR]

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.
