Hello Levaske,
Thanks for using Apple Support Communities.
I see from your post that you're trying to find the iTunes Match menu in iTunes. With iTunes 12.2 and the introduction of Apple Music with iCloud Music Library, iTunes Match has been incorporated with the iCloud Music Library. You can access the setting for this in the iTunes Preferences as shown below.
On your Mac or PC:
- Make sure that you're signed in to iTunes with the Apple ID and password that you use for your Apple Music membership.
- Mac: From the menu bar at the top of your computer screen, choose iTunes > Preferences and turn on iCloud Music Library.
Windows: Press Control + B on your keyboard to open the iTunes menu bar. Choose iTunes > Preferences, and turn on iCloud Music Library.
- If you already have music on your device, you'll be asked if you want to Merge or Replace the music. Choose Merge to add the songs currently on your device to your library.* If you select Replace, the music on your device is replaced with your Apple Music library.

Take care.
