Ah! That may be the issue. WikiTree can't accept or store any type of DNA raw data, so there is no place to upload anything.
What WT does store is basic information about any tests that you've taken. You do have the fact that you took an FTDNA mtDNA test on your profile, but what you'll likely want to do is edit that to add a bit more information about the test.
From the menu at the top of most any WikiTree page, go to Add > DNA Test Information. Test info you've already entered will be displayed, and you have the ability to edit any of that or to add a new test. Here's what I see when I look at my mtDNA test:
On your profile, click the dark-green button beside your mtDNA test labeled "Edit or Enter More Details."
The haplogroup field is just typed-in text. Your haplogroup should be entered as FTDNA reports it. In most cases, that will be an upper-case letter, followed by a numeral, followed by a lowercase letter, followed by another numeral...and so on. The length of the haplogroup designation will vary. When I mentioned spaces earlier, one thing to be cautious about is not entering a space before or after typing in your haplogroup.
The next field is to specify what type of mtDNA test you took. That's selected from a pull-down menu and will likely be "Full Sequence."
You can also enter your FTDNA kit number, if you want. And if you have a mitoYDNA (https://www.mitoydna.org/) account, you can enter that ID, as well.
There is a free-form comment field, and you can see in mine that I chose to enter the values in my results that differ from the RSRS standard. This isn't typically done; in my case, I don't mind listing these as a shortcut for any interested researchers. But it's the comparison of the full sequencing information--what you find in your FTDNA dashboard--that's of the greatest genealogical value.
If you have a mitoYDNA account, you'll enter something similar there, but that will use a different reference model called the RCRS. You can get those values from your FTDNA results. These are what mitoYDNA uses to compare your results with others in their database. Another advantage to mitoYDNA is that WikiTree members can link directly over to mitoYDNA to compare results.
Hope that provides at least a little assistance. If not, hop back over here and post again. If not me, someone is sure to see it in short order.
