Hi! You posted your question in the non-technical Lounge forum, which is where you can connect with your peers for conversations that don't directly relate to product help and support. I'll move your question to the InDesign forum so that you can get the answer you are looking for.
P.S. For a list of all available product forums, see https://forums.adobe.com/welcome/
The Sync feature has been depreciated. as per Synchronize settings using Creative Cloud
The only way to sync items and styles is to use the Library. It will sync with the computers you login to with the same Adobe Cloud account.

Thank you so much for your help! This worked, thank you!!
