I am trying to edit information I accidentally entered. When I press the "revisit" button, the website does not go to the next page so I can delete the information.

Click on the FORMS button on the bottom of your screen.  This will take you to the actual tax form from where you can manually delete the unwanted entry.

You can delete the form directly in TurboTax Online-

 To Delete a form:

1. Select Tax Tools from the menu on the left
2. Then select Tools
3. When the new menu pops up select Delete a Form
4. You will see a list of all the forms in your return
5. Find the form that you want to delete
6. Select the Form
7. Click Delete on the right 

Tax forms are interconnected.  While you are on this screen don’t start deleting forms you don’t recognize.
