Not unless we tell you to. The goal of e-filing is to
eliminate as much paperwork as possible. There are a handful of situations where you might have to
mail something after e-filing, for example if your return contains Form 8453. If yours is one of them, we'll let you know. Otherwise,
don't worry about it. We do recommend that you print your return for your
records after your e-filed return has been accepted.
