Minecraft 1.13 find treasure?

I found a treasure map, went to the X and dug a pretty wide hole in the sand, which is about 5 blocks deep, but I have not found anything, how and where to dig to find the treasures?

I recommend a 25 * 25 wide and 15 min deep hole ^^

If you are desperate, you can enter this command:

/ locate Buried_Treasure

Just put it near it and enter it. Wait a moment and click on the green text that appears in the chat and press enter.

Hope that helps you!
