"It seems to have filed...." Did you click a big orange button that said "Transmit my returns now?" The tax return was not filed unless you did that. What does it say in your account? Does it say "accepted?" "rejected?" "printed?" or "ready to mail?" If it says anything other than "accepted" it has not been filed.
If it has not been filed, you can click on "Add a State" so that it will let you back in to enter information or make changes. You do not really have to add another state, but that trick will let you back in to the return.
