Mark,
It appears you added all these profiles, but have not linked yourself thru these lines to a main branch of WikiTree. Unless you had your family test and own their profiles here on WikiTree and share their DNA, those would be the only tests you would see.
What you must do is connect your tree to a branch here on WikiTree. All us test takers are available to you if you continue to connect to us here. Look if you may have duplicated a profile page of one of your ancestors. Or perhaps going up one more level, will connect you with one of our branches.
Once you connect to a branch, that line you have connected will, or should have some DNA test takers that are sharing. Only until you connect your profiles with ours, will you see matches.. Right now you are on an island with your tree by yourself. Come play with us!
