TurboTax Online does not let me edit a return that is not yet filed

I tried to post this question awhile ago, but I did not see it in the forum.

I filled in most of my return using TurboTax Online. At the end I selected "mail" as the filing option, but also "Not ready to file" so that I could print it. I printed it and then changed the filing method to "electronic". However, I still kept the "Not ready to file" selected thinking I could change anything. It will not let me edit anything now, but I need to change a pension entry. I have not filed it yet, I just need it "unlocked" so I can edit it and file it electronically.  

This should not have to be an amended return. It hasn't been filed! How do I unlock it?

Thanks for your help
