If only one DBT has been successfully submitted for the current day (12am to 11:59pm PST), you cannot delete it because at least one DBT must be selected. However, you can edit (see “How do I edit a DBT?”) or replace it (see “How do I add or remove a DBT?”) with a different DBT.
If more than one DBT has been successfully submitted for the current day (12am to 11:59pm PST), you can delete all but one DBT. Click the “see more” button on the completed DBT you wish to delete, then click on the trash can icon to delete it.
Note: You can only delete or replace a current day DBT (12am to 11:59pm PST), all historical DBTs are locked.
