Location of sky replacement presets located on my Mac?

[#1]

I would like apply some noise reduction and sharpening to some of the replacement sky presets but I can't find where they are stored on my Mac (Mojave.)  I've looked in Users/Library/Application Support/Adobe/Adobe Photoshop 2021/Presets/Skies, but it's empty. Any help would be appreciated. Thanks
