I need help with Brewing Recipe

I made a custom potion and i wanted to make a custom brewing stand recipe for it.

First of: I cant find the awkward potion neither my own potion wenn selecting the base potion and the resulting potion

Also I looked through so many tutorials and none of them work.

So i could really need a "template code" for a brewing stand recipe or a tutorial for how to make a brewing stand recipe in 1.16.5
