If a girl has an above average amount testosterone in her body, will she grow longer than girls with less testosterone?

The major mechanism of height gain during growth (namely, puberty) is the growth plate elongation.

Estradiol (estrogen) action closes growth plates (somewhat), preventing further elongation of the long bones. Excess testosterone will likely be converted to estrogen by aromatase (which isn't near saturation in normal physiology) in females. This enzyme is also more abundant in females. Thus, testosterone will likely cause *shorter* women.

However, testosterone post-puberty leads to more active bone-forming cells. Thus, the bones are actually stronger (low testosterone is one cause of male age-related bone loss).
