I checked the status as you suggested and nothing was uploading. I purchased the AnyTrans app and after two tries was able to transfer the music files from my iPhone to my MacBook Pro. After that, I was able to upload the music files from my MacBook Pro to iCloud Music using my iTunes Match subscription.
Then I ran into a problem sharing the Music Library with family members. Part of the problem may have been caused by one family member having an inactive Apple ID. I contacted Apple Support and they reactivated the Apple ID and I was able to delete the family member.
But I was still unable to share the music on my wife's iPad and iPhone. This problem was fixed when I went into the settings on her iPad and under Music changed the Apple ID that is linked to music purchases from her Apple ID to mine. Fortunately, she had never used Apple Music so no music was lost. Bottom line - everything is up and running and we're working on making some play lists for our next road trip. Thanks for all the help.
