Greetings tatiana_maxwell123,
It sounds like you’re able to see the projects listed as if they are recent projects by right/Secondary clicking the app icon. How about if you launch the GarageBand app and attempt to locate the files through Finder or iCloud Drive that way? Create and save projects in GarageBand on Mac
Open an existing project
1. In GarageBand on Mac, choose File > Open (or press Command-O).
2. Locate and select the file, then click Open.
You can also open a GarageBand project by dragging it onto the GarageBand icon in the Dock.
If you haven’t already, you can also try to use the Search/Spotlight functionality on your Mac to search your Mac for the files by name - Search with Spotlight on Mac This article also has a screenshot you may find helpful as it points out and defines some of what you may be seeing in the results.
Search for something
1. On your Mac, do one of the following:
• Click the Spotlight icon (if shown) in the menu bar.
• Press Command-Space bar.
• Press (if available) in the row of function keys on the keyboard.
You can drag the Spotlight window anywhere on the desktop.
2. In the search field, type what you’re looking for—results appear as you type.
Spotlight lists top hits first; click a top hit to preview or open it. Spotlight also suggests variations of your search; you can view those results in Spotlight or on the web.
3. In the results, do any of the following:
• See results of a suggested search in Spotlight: Click an item preceded by the Spotlight icon.
• See results of a suggested search on the web: Click an item preceded by the Safari icon.
• Open an item: Double-click it. Or select the item, then press the Return key.
• Show the location of a file on your Mac: Select the file, then press and hold the Command key. The file’s location appears at the bottom of the preview.
• Copy an item: Drag a file to the desktop or a Finder window.
• See all results from your Mac in the Finder: Scroll to the bottom of the results, then click Search in Finder. To refine the results in the Finder, see Narrow your search results.
Thanks.
