If I bought out my partner in an LLC last year, how does that "income" get reported to my partner? Does the LLC report it on the 1065/K1 or by some other method?

My business partner and I were each 50/50 partners on an LLC until December 31st of last year.  At that point, I purchased his "shares" (LLC units) for $X and then owned the LLC 100%.

How does the $X get reported on the business or personal taxes?  I couldn't find anywhere in TurboTax (Home & Business) to report it, and I'd have to believe that it gets reported somewhere for both of us.

As well, the profit that was made last year up until the point I bought his shares would be split on our taxes as well?
