Deductions & credits
Yes, you enter the code V and leave the box blank, but it is very important to Continue through the K-1 interview after you have entered your code V on the box 17 screen. There is a screen near the end of the interview titled "We need some more information about your 199A income or loss". This screen must be completed with the box 17 code V Section 199A Statement or STMT that came with your K-1, in order for your QBI deduction to be calculated.
And, depending on what is reported on your Section 199A Statement/STMT, you may need entries on the next "Let's check for some uncommon adjustments" screen as well.
To get back to the K-1 summary screen and find the Schedule K-1 to edit, click the "magnifying glass Search" icon on the top row, enter "k-1" in the search window and press return or enter, and then click on the "Jump to k-1" link to find the K-1 you need to edit.
Here are screenshots of the two screens to enter your Section 199A Statement/STMT information:
