You have dust on the focusing screen under the pentaprism.

Try to ignore it - it is harmless and has zero effect on your images. If you feel you can't tolerate looking at it, try blowing it off the screen with a bulb blower or a lens brush.

Remove the lens and look up to the top of the mirror box. Don't touch the mirror. It is a front surface mirror and easily scratched.

Look up under the pentaprism housing, and the white, lined area is the focusing screen. It is not removeable on a 20D according to the factory. That is where the dust you see in the viewfinder is hiding. Use a rocket blower or a lens brush or a sensor brush to carefully clean the screen. Do not be to obseessive about cleaning it. Just get it back to tolerable to look through and you are done.

Where is the pentaprism.

It it the pentagonal thing that sticks up in the center of the top of your camera.
