How do I modify Schedule 3? I should not have an entry on line 12e, but I do, and I cannot modify the form.

Line 12e was autofilled with $13. When going thru the worksheet manually, this figure is correct, however, I do not want to defer the self-employment tax of $13. It is not worth the trouble of tracking this. I want to remove this figures, and delete Schedule 3 because the figure on line 12e is the only line on the form. I have tried to delete the Schedule 3 using Tax Tools, Tools, Delete a Form. It tells me that the form has been deleted, but it's still there.
