This is for PS 23.3.0 Release on Windows 10.

I'm trying to save a TGA file with an alpha channel (it is properly created). For some reason, the alpha channel is only saved if I save it using 32bit/pixel color depth, which should be unncessary. For 16 or 24 bit selections, opening the saved TGA will result in only the RGB channels.

Yes that's as designed and explained here from the photoshop cs2 help manual

(unfortunately the photoshop cc online help does not explain this)

In this case 32 bits/pixel means a 24 bits/channel document (three 8 bit rgb channels) plus an extra 8 bit channel (alpha channel) which gives you the 32 bit/pixels.
