True Polymorph causes the first target permanent to copy the printed values of the second target permanent, including any copy and mutate effects that have been applied to it. It won't copy counters on that permanent or effects that have changed its power, toughness, types, color, and so on.

True Polymorph's effect does not have a duration. The copy effect it creates lasts as long as the first target remains on the battlefield.
