Hi Kimberly, You're off to a good start: on your profile you've entered the information about the DNA test you took. And you've entered profiles for your parents, grandparents, etc. If other people on WikiTree who are related to you have taken autosomal DNA tests, and have also entered the information about their DNA tests here on WikiTree, that information will automatically appear on your profile. That process only happens once a day, so won't be there instantly. I don't see any one else's DNA tests displaying on your profile so far.
If you find people who match you on GedMatch.com, you can send them links to your WikiTree tree so they can look for your shared ancestors. You can encourage them to enter their ancestors on WikiTree also to help you figure out the connection.
