There are a few reasons why your contacts might not be saved to iCloud. One possibility is that you have iCloud turned off for your Contacts app. To check this, open the Settings app and tap on iCloud. If the Contacts switch is turned off, turn it on and see if your contacts are now syncing to iCloud. Another possibility is that you have "Optimize Storage" turned on for iCloud. This can be checked by going to Settings > iCloud > Storage. If this is turned on, your contacts will only be saved to iCloud when space is available. To fix this, turn off "Optimize Storage" and ensure enough space in your iCloud Account to save your contacts. You can try resetting your iCloud account if you're still having trouble getting your contacts to sync to iCloud. This will delete all the data in your iCloud Account, so be sure to back up any important data before doing this. To reset your iCloud Account, go to Settings > iCloud > Delete Account. Once you've deleted your Account, you can set it up again and see if your contacts are now being saved to iCloud. If you're still having trouble, there's possibly a problem with how your contacts are saved to iCloud. You can check this by going to Settings > iCloud > Advanced. If the "Contacts" option is set to "All Contacts," try changing it to "My Contacts" and see if that fixes the problem.
