Exactly how have you been reporting your gains and/or losses on this investment each tax year over the last 10 years? Did you receive a K-1 each year? If so, what kind of K-1? I figure it would be 1065 K-1, but it could just as easily have been an 1120-S K-1 also.
What kind of an owner or partner were you in this venture? A limited partner? controlling partner? Managing partner? Something else?
