Yeah I think you are an INTP since you're 5w4 it's pretty fitting. and common for your type.

Basically there are introverted functions and extroverted functions which for Ti and Te as an example Ti thinks logically with internal logic structures everything is inside of their head and they test new information with their internal logic change, where Te thinks largely with external forms of logic.
Where the Ti person would rather sit and think deeply about how to put the puzzle together before trying the Te person will smash together pieces until they find what fits.

That similar process of Introversion vs Extroversion happens for each of the 4 main functions, and there tends to be one function which each user uses much more than the other functions which is considered your dominant function
