If these waves travel at the speed of light shouldn't the distance and time match up...?

This would be true in a static universe, but, during the 1.2 billion years the waves have been traveling, the universe was experiencing accelerating expansion.

For example, the edge of the observable universe is about 46.5 lightyears away, while the universe is thought to be 13.8 billion years.

I assume you mean 46.5 billion?

Yeah, thanks! I can't edit it any more, unfortunately.

Not if space time it'self is stretching while the light is in transit.
