William, you said your tree is a mess, but on WikiTree you don't appear to be connected to any ancestors. I suggest you add them one by one, checking your documentation and adding your sources to the profiles as you go along. After a while, you will most likely be able to connect yourself to the "main tree."
Meanwhile, you can add your DNA test information to WT as I think others have described.
Your DNA matches may be easier to identify after you've created an accurate tree.
Good luck! Feel free to send me a WT private message if you want more help.
Edit: I see now you are connected to a living father and have uploaded a gedcom, but apparently you haven't processed it yet. I think my advice above still applies.
