Only after 20 years. Light will take 10y to make it from earth to the mirror, and 10y to travel back.

No, the light would be reflected as soon as the mirror is set up. If the mirror is set up 10 lightyears away it would take 10 years for you to see it and whatever it reflects. There already is light on the way to the position of the mirror before you set it up.

Oops, that's right!

it takes way more than 10 years to ship a mirror from Earth to some place 10 ly away from earth.
