I accidentally clicked a wrong button when asked if I wanted to file a Form 2210. Now it keeps popping up when I am trying to finalize my return. How do i get rid of it?

You can click on "Tools" in your menu bar and the "Tools Center" box would pop on your screen.

Choose "Delete a Form"

In the forms view locate the form you need to remove and click "Delete" next to it

Confirm you want to delete the form and continue on to e-file.
