How do I know the Y value when running the locate command?

I'm trying to find a woodland mansion in creative, but I need help with the Y.

When I run /locate, it says at block 1576 (y)? -11176

How do I know where to go if it won't tell me the Y value?

Locations using the /locate command never give y values. It doesn't matter, just run

/tp @s 1676 100 -11176

and you should be there. Whenever you use the /locate command, just teleport yourself to y 100 and then dig down until you find your structure if it's something like an abandoned mineshaft.
