I have never used Behance before, nor set up an account. However, when I clicked on the Behance link from "Creative Cloud Help / Creative Cloud and Behance FAQ", it shows my profile.
Do I have a Behance account or not?
Hi Carol - yes, it does look like you have a Behance account here: https://www.behance.net/CarolV
If you'd like to login, just visit Behance.net, click the red "login with Adobe ID" button, and you can go from there.
Let me know if anything else comes up!
Thanks for responding - I really appreciate it. I've just about given up on getting responses on Adobe, so this is very very welcomed.
