Do I still need to mail in a copy of my tax even though I e-filed? If so, does it have to be don't by the 18th? How do I pay the state tax?

You do not need to mail in your returns if you e-filed them and they were accepted. You can either send a check into your state for the amount due, or you can see if your state accepts payments online (visit their department of revenue website).
