Wikitree does not accept RAW DNA data!!
Wikitree only needs the details of your tests which you have already submitted.
It takes up to 30 hours for those details to propagate its way through the tree - when your profile is connected.
At this time your profile is not connected to the global tree so you won't get any "matches"
The sooner you add some ancestors and get yourself connected to the wikitree global tree, the sooner you can find out to whom you may be related.
I would recommend that you upgrade to a family membership and start adding your ancestors. The family membership no cost to you.
I would also like to welcome you to WikiTree and hope you enjoy it as much as I do.
