| We've started using this expression 4 years ago |

Passive:
1) This expression has started to be used 4 years ago.
2) This expression has started being used 4 years ago.
3) This expression has been for 4 years now.
Are 2 and 1 both correct?
Does 3 consider to be a correct rewrite or I it must include 'started'?
Thanks
