What should I do if a form I tried deleting will not delete?

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

1. Open your return in TurboTax. (To do this, sign in to TurboTax, and select the Take me to my return button.)
2. In the left sidebar, select Tax Tools then Tools.
3. In the pop-up window Tool Center, choose Delete a form.
4. Select Delete next to the form/schedule/worksheet and follow the onscreen instructions.

Refer to the TurboTax help article How do I view and delete forms in TurboTax Online? and How do I delete a tax form in TurboTax Desktop? for more information.

Forms will automatically regenerate if information required to be reported on that form has been entered elsewhere in TurboTax.  Either the form is required or you have made an erroneous entry of the information that is required to propagate to that form.  You can examine the automatically generated form to see what information is propagating from elsewhere.
