The values for mouseX and mouseY in SDL_MouseWheelEvent are relative to the render output size not the logical window size. In the other events like SDL_MouseMotionEvent the x and y coordinates have been converted to the logical window size.
This feels like a bug, the mouse wheel position should also be translated to the logical window size.
I tested this in 2.28.5
Windows 10
with direct3d11 renderer
