Your next step is to upgrade to family member. Then you can add a profile for your brick wall ancestor. When you do, come back here to the forum and post a link or ID number. You will find the Wikitree community friendly and helpful and they love to help with brick walls.
You will also want to check out the project list. Projects are a great way to learn more, discover new resources and collaborate with other members. The project list can be found under the Find drop down menu.
