You posted your question from online Deluxe.
There is no Forms mode in online TurboTax. Forms mode is a feature of only the CD/download software.
If you have changes to make you have to use the interview screens to get to the right places. And....if you want to e-file, you have until Monday, October 17, or it will be too late to e-file and your return will have to be filed by mail.
