How to recover TOC Styles after full CC reinstall

I have recently had to reinstall the full CC suite, which included the usage of the Adobe CC cleaner. 

Now, in InDesign, I see that my TOC Styles are missing. I was sure that they would have been there when exporting user settings and then importing them back but, apparently, they are not. 

Where could I find them? I have plenty of Time Machine backups, CCC clones, and documents where those styles existed so I hope you will be able to tell me how to recover them. I was hoping for a “Load TOC Styles” button but no, there is not.

Thanks!
