To add your DNA test information to your profile, from the drop-down list under 'Add' at the top right of your profile, select 'DNA test information'. That will take you to a page where you can enter information about any DNA tests that you have taken. Once you've entered the information, scroll down the page until you get to the button that says 'Add Test for ... (your name)' and click on the button. DNA test information is only updated once a day, so depending on the time of day you enter the information it may be a day or two before you see the information displayed on your profile.
You haven't added your parents (or any other ancestors) to WikiTree, so WikiTree won't be able to display your test information on any profiles except your own.
