@RenasaiHaru was there any instructions in the troubleshooter? The way I understand the cloud saves is that they are automatic, as in when you save on your console it saves to the cloud unless you are offline. So I am uncertain if there is a way to manually check it. If you have been signed in to Live the whole time, the saves should be synced to the cloud.
https://beta.support.xbox.com/help/games-apps/game-setup-and-play/cloud-game-saves-faq says it's automatic "While you’re connected to Xbox Live, saved games are automatically stored in the cloud. If you use your Xbox profile to sign in to a different Xbox One console, your saves are available from that console."
Edit: I believe the saves are synced when you log out of your profile or turn off the console on XBox. So you can sort of force the sync that way.
