Which episode of Young Sheldon did Melissa Joan Hart
Direct? I know she directed one.

She directed this episode:

An Academic Crime And A More Romantic Taco Bell-Dr. Sturgis is furious when Sheldon accuses him of plagiarism. Also, Mary sets out to find a "girl trophy" for Missy's end-of-season baseball ceremony, and Georgie has an awkward run-in with Veronica while on a date with his new girlfriend, Jana.

God bless you and her always!!!
