I just made a chart of type results I've got from tests during the 9 years I've known about typology, and just 5 results seemed to be missing.
Then I remembered I got INFP one time.
That left all the 4 xSFx types, which I've never got as a result. Incidentally, they're opposed to the xNTx type results which I've got the most.
So, what isn't your type?
