2. Select Check.
3. Choose the small icon with the counter clockwise arrow in the top left corner.
4. Click the duplicate check to open it from the Recent Checks list.
5. Select More at the bottom of the page, then Delete.
6. Choose Yes to completely remove the check.
That will do it. I'll be here if you have any other questions, just let me know by commenting below.
