Why does a deleted form keep showing up

There may be a related form or worksheet still in your return that is causing the deleted form to re-appear. Follow the procedure below, which I suspect you have already used, but take care to look for and delete any supporting forms or worksheets first, then delete the main form. 

For example, if you are trying to delete a Schedule C, delete all related asset worksheets, depreciation schedules, miscellaneous expense lists, etc., before deleting Schedule C itself.

Here's the general procedure for deleting unwanted forms, schedules, and worksheets in TurboTax Online:

• Open your return in TurboTax. (To do this, sign in to TurboTax, and click the orange Take me to my return button.)
• In the upper right corner, click My Account and select Tools.
• In the pop-up window, select Delete a Form.
• Click Delete next to the form/schedule/worksheet and follow the onscreen instructions.
• Repeat, as needed until all the unnecessary forms, schedules, and worksheets have been removed.
