I was a 51% partner in a LLC business that on only operated about 3 months of 2016. Im trying to file my taxes myself on turbo tax i know i need to file a 1065 but where is the K1 form suppose to come from? i didn't do i a large amount of business in 2016 but did have quite a bit of expenses that id like to write off.

The Schedule K-1 should come from the partnership. It is part of the Form 1065 filing. Since you were the majority partner, the answer is probably that the K-1 is coming from you.
