Have you completed all the steps for importing a GEDCOM into WikiTree? You need to take a GEDCOM on your computer and download it to Wikitree, then you go through it using the tools on Wikitree to find matches, etc. and get the ok from the GEDCOM checker and then you have to do the actual import after which you can access the profiles which are created and start cleaning them up and adding sources to those which don't have any, etc. If you haven't gotten to the Import step yet, you should read all the pages in Help Index to get familiar with what you have to do. Lots of times people think that once their GEDCOM is approved they're done and don't realize they have one more step to do.
