It says “ready to mail” tax returns etc. was I supposed to mail my tax returns to the IRS? I thought doing it on here would mean it was already electronically submitted ?

You need to Select to E-file your return in order to send it electronically, otherwise you need to mail it in. 

Since you didn't mail the return yet you can change the filing method to e-file.

1. Log in to your account.
2. Select Add a state (you won't add a state;just to open the return).
3. Select File from the left menu and go to step 3.
4. Select to e-file the return.

If e-filing is not an option, you might have some forms or schedule included in your return that can't be e-filed. In that case your return can't be e-filed and you need to mail it in.
