A partnership changed it's accounting method two years ago. Because of that there is significantly more cash in the business than has yet been recognized as revenue. The partners have withdrawn significant amounts of this cash as distributions, but because it has not yet been recognized as revenue, they have distributed more than their basis in the partnership. How do I show this on the return? Where do I deal with it on the Sched L, M-1, M-2?  If it is a capital gain, is there a way to show this on the tax returns so that everything reconciles? Right now, I am showing a negative basis, and so I cannot e-file. Just not sure how to deal with this, how to keep the basis at $0 - what happens with the rest on the return, and how do I make it pass through to the owners?
