how do I delete forms while amending a return?

I'm using turbotax online to amend a return, and am in a situation where I need to delete some forms that I had added. (Initially I added form 2555 to the amended return, but now want to remove it, which necessitates manually deleting some worksheets.)

 

There is no "delete a form" under "Tax Tools".

Furthermore, if I "Cancel Amend" and try to start over, turbotax remembers all the changes from the cancelled amend, so the problematic forms are still there.

 

It's maddening-- I suppose I'll be told there isn't a way around this, and now have to download turbotax desktop.
