Where does the saying, "that describes you down to a T" come from and what does the "T" actually refer to ??

The 'tittle' suggestion in the above link is almost certainly the right derivation, one meaning of ‘tittle' being the cross-mark on the letter 't' and other such small elements of writing such as dots. The Oxford English Dictionary rejects all of the other so-called possibilities as untenable.
When writing in a hurry, one often omits the cross-stroke of a 't' or the dot above a ‘j' or ‘i', so 'to a T' suggests something is exactly right.
