The exact location may vary depending on your operating system and version of Lightroom, but here are some common locations:
On Windows: C:\Users[your username]\AppData\Roaming\Adobe\Lightroom\Develop Presets
On macOS: /Users/[your username]/Library/Application Support/Adobe/Lightroom/Develop Presets
If you still can't find your presets, you can try searching for files with the .lrtemplate extension on your old computer. These files contain the preset information and can be copied to your new computer and placed in the appropriate folder.
