Origin:
The origin of this idiom, first observed in 17th century, is unsure, & its connection with either a golfer's tee or a T-square of a builder are not impressive. It might be that the basic idea is that of completing the letter T by putting in the cross stroke, but the early 17th-century to a tittle was similar in meaning, and T might have been used as an abbreviation of tittle. The related phrase “to a tittle” is found in a play, The Woman Hater by Francis Beaumont and John Fletcher (“I'll quote him to a tittle”) acted in the year 1607.
