Thank you for your response. This doesn't work because TT thinks my return is finished/closed. But I have not mailed it. When I follow the steps, it shows federal return $0, and nothing can be changed...
When I look under "Your tax returns and documents", I see "Filed Federal Tax Return, return status: Printed." That can't mean TT sent my form away, can it? That would be very bad because I had extra forms to append.
