first of all, there is pretty much no chance at all that you are xxTJ. you tested 17.6 on Te. that's worse than average. actually, that's pretty terrible. (it's worse than my score, and i consider myself a Te cripple.)
you scored high on 4 functions.
Se, Ni, Fe, Fi
you say you're an extrovert. so let me do some Ne/Ti-ing for you.
you are either:
ESFP (Se and Fi)
ENFJ (Fe and Ni)
if you're ESFP, you're Se dominant, meaning you notice details better than most, and you like the feel of action in the present moment. Fi relates present experience to "what's good for you"
if you're ENFJ, you're Fe dominant, which means you focus on group dynamics -- you see how people relate to eachother and you focus on group harmony. Ni gives you insight into what other people's perspectives are, giving your Fe function a dynamic twist.
some advice:
1) type descriptions are terrible (unless they're based on function interactions). don't listen to them.
2) 99% of MBTI tests are terrible. they test things against eachother that are not in opposition. for example, they might test Ti against Fe, which means you're gonna lose points for one or the other even if each of them are well developed.
and listen. you took a test that tested for strength of Te. it did not test Te against any other function. it measured Te against 'not Te'. and you were closer to 'not Te' than Te. clearly not xxTJ.
