The K-1 get entered as in previous years. During the entry of the K-1, you will get a question asking if you "disposed of a portion of my interest during 2019". When you select that box, TurboTax will walk you through the sale.
To enter the K-1, click the "magnifying glass Search" icon, enter "k-1" in the search window and press return or enter, and then click on the "Jump to k-1" link to begin entry of the Schedule K-1 you received from your farm.
