This makes sense as you don't really have a disposition.
Not sure if your Line L is marked "tax basis", if it is great. If not, hopefully you are maintaining this as your tax basis will carry over.
Your suspended losses would free up if this was a complete disposition, but since it is not, these will carry over to the new LP. You will need to eliminate these from the "old" and input them in the "new". I believe there are some options to "eliminate" the "old" K-1; choose other disposition. Will ask for some details regarding disposition. Just input some figures that reflects no gain or loss; proceeds equals basis.
