Question

How can I delete an unneeded form?

I'm stuck in a "Check this Entry" for a blank form that I do not need.

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

Open or continue your return in TurboTax.
In the left menu, select Tax Tools and then Tools.
In the pop-up window Tool Center, choose Delete a form.
Select Delete next to the form/schedule/worksheet in the list and follow the instructions.
