Click the Apple logo in the top-left corner in the menu bar. A drop-down menu will appear. It's in the drop-down menu. The System Preferences window will open. It's on the left side of the window. Doing so opens the iCloud window. If you're not automatically logged in, enter your Apple ID and password in the middle of the window. In the middle of the window, you'll see a list of apps with checkboxes to the left of their names. Checking the box next to an app will synchronize its data with iCloud.  By default, all of the apps in this window should be checked when you sign into your Apple ID. Whenever you use a synchronized app, any data you enter or changes you make will be updated in iCloud and any other iCloud-synchronized items (e.g., iPhones). To access your iCloud Drive on Mac, open the Finder and click iCloud Drive in the pane to the left.
