Tonya is a character in Young Sheldon and was portrayed by Sofia Rosinsky.

Her uncle is Pastor Jeff Difford. During the summer, she was sent to Medford, Texas because her mom found out she had a boyfriend named Zach and freaked. She went into Video Village and talked to Missy Cooper, who together rented the film Point Break while under another film case. They hung out at night and smoked while walking out. At night, they got scared by Dale, who was protecting the video store from any possible future intruders.

Her uncle found out about the film, but not the smoking of cigarettes, and was embarrassed by that action. (German for Beginners and a Crazy Old Man with a Bat)

Tonya hung out with Missy again and they went home again so late at night. The next day, she was at Missy's house to hang out. She was asked by Sheldon Cooper about where they went, but she refused to say anything, to him. Later, Sheldon blabbered to his parents, and they called her uncle Jeff to pick her up. She was forced to apologize and left, saying she wanted to go to her fun uncle Jerry's place. (A Romantic Getaway and a Germanic Meat-Based Diet)
