Minecraft wiki entry for Acquiring_a_conduit, associated text: Buried treasure maps are usually blank with a white indicator dot. This shows where the player is in relation to the buried treasure. Remember that upward on the map is north and rightward on the map is east. As the player gets closer to the treasure, the indicator dot increases in size until they start filling in map features. Traveling may involve a long boat ride. Upon reaching the red "X" use a shovel to start digging 2×2 or 2×3 around that area to find the treasure chest. A more convenient method is to dig straight down the center of the chunk when at the red "X" (chunk coordinate 9,?,9 in Java Edition, 8,?,8 in Bedrock Edition), because treasure chests always generate in this certain position in a chunk. A buried treasure chest always contains a heart of the sea.
