@anna  - Which is NOT me.....why the *no* vote for a 100 % accurate answer ?

At least, based on the question you initially asked, not the revised version:

"I need to delete the k-1 for a partner who withdrew from the partnership in 2018. How do I do this?
He actually withdrew from the partnership at the end of 2017... thus, his information is in the program and I'm not sure how to get it off."
