Your K-1 will have an attached Section 199A Statement with the amounts needed to calculate your QBI deduction. The info for your QBI deduction is associated with a certain box and code on your K-1, depending on the type of form you have:
Box 20, Code Z - Used for Partnerships (Form 1065)
Box 17, Code V - Used for S corporations/Shareholders (Form 1120S)
Box 14, Code I (as in India) - Used for trusts/Beneficiaries (Form 1041)
Once you enter your K-1 information into TurboTax, the QBI deduction will be automatically calculated for you.
