The coordinates for a desert temple are actually for a witch hut.

1.Run the command /locate temple.

2. After the coordinates pop up, run the command /tp @s <your coordinates here>.

3. After you have been teleported you would see a witch hut, instead of a desert temple.

 

When running the command "/locate temple", the coordinates that pop up don't teleport you to a desert temple. Instead, they teleport you to a witch hut. I have tried it on a lot of seeds and it does the same thing.
