I'm sorry, I should have been more clear.  I have entered all of my K-1 information already, but I found out today that since I have received distributions in excess of my stock basis that I have a capital gain to report.  But I can't figure out where to enter that?

Distributions in excess of basis are capital gains.  You would report this as if you sold sold, so the information goes on form 8949 which will then go on Schedule D.  

Assuming you purchased the stock all at the same time, just enter the date purchased.
