the most common idea is cloud cities, this could be done fast and needs no terraforming
another approach is to shield Venus from sunlight with some giganormous umbrella and freeze out carbon dioxide from the atmosphere, this would take at least 300 years and and you only get a deep frozen planet with dry ice
to turn Venus in a second Earth you need plate tectonic, there is some volcanism so it's possible, but naturally it would take more then a million years, maybe we can speed it up by crashing asteroids into Venus but how would we do that?
