Switch to Forms Mode in your desktop software (should be an icon that says Forms). Scroll down through the forms on the left-hand side until you get to the PA section. Find Schedule UE in the list and click on it. Review the form to make sure that there is nothing on there that didn't get accidentally entered somewhere. After you click on the form, you should see an option to Delete a Form at the bottom. Delete the form and this should remove it from your return.
If the form pops back up, then that means something was entered - likely in the Federal Deductions and Credits - Job Related Expenses section. Maybe a blank form was created there and you may also need to delete Form 2106.
