Sold farm in 2016.

TurboTax carried forward the K-1 because your 2016 tax return did not report your 2016 K-1 as the "final" K-1.  

The proper way to delete an unwanted K-1 is from the K-1 Summary screen, which also removes the associated worksheets.

1. Open or continue your return in TurboTax, if you haven't already.
2. Using the search feature in the upper right, search for K-1 and select the Jump to link in the search results.
3. Answer Yes to Did you receive any Schedules K-1 or Q? Select this even if the correct answer is no.
4. Select Update next to the type of K-1 you initially entered (partnership/LLC, S corp, or estate/trust).
5. On the K-1 Summary screen, select Delete next to the K-1 you want to remove. Answer Yes on the following screen.
6. Select Done.
7. If necessary, repeat steps 4–7 for other K-1s you need to remove.

Thank you, problem solved.
