Someone asked me the same question only recently, but up until that time, I
had never heard of such a thing.  It seems to be a myth that somehow got
started recently and is now being circulated.  Aaron Burr, the
vice-president who served during Jefferson's first term, was involved in a
duel with Alexander Hamilton, of course.  But I know of no authentic source
that suggests that Jefferson himself was involved in a duel or acted as 
executioner for someone accused of treason.

For locating information on dueling during the years of the early republic,
I would recommend that you go to a good search engine, such as Google
(www.google.com) and try there using key words.
