I doubt the Depot will have a 12-32 tap, probably a miss label.
This is along ago special size with virtually no fasteners available.
What is the purpose?

Tap drill should follow the classic formula: OD minus distance between threads (ie, 1/pitch).
OD - 7/32 = 0.21875"
Distance = 1/32 TPI = 0.03125"
Tap drill = 0.21875 - 0.03125 = 0.1875" = 3/16" drill
