how to get Itunes to transfer music to my devices

I assume by Apple Macth, you mean iTunes Match, rather than Apple Music.

If so, make sure Sync Library is turned on in iTunes on your computer and iOS devices and that your music has been uploaded to the iTunes Match cloud.

What do you mean, "when I go to devices"?

You cannot physically sync using the main sync button in iTunes when using the iCloud Music Library from iTunes Match.

That Sync above button will do nothing when Sync Library is turned on. As that option renders the direct sync option unnecessary.

If you have turned on "Sync Library" in Preferences. Then tracks in your libray on your computer are scanned, and either matched or uploaded to iCloud

Once that is done, turning on the Sync Library option directly on the iPhone or iPad should show the tracks in the Music app there.
