Depending on the way your tutor has setup your assignment, you may be able to overwrite submissions until the assignment due date. You can check with your tutor to see if you they have allowed you to submit multiple times or not. Once you know you can, locate the Turnitin Assignment in your module. Click 'View Assignment' and there will be a 'Submit' button on the next screen which you will have used for your first submission. All you need to do is repeat the process again by clicking this button and make a new submission, and Turnitin will overwrite the existing assignment.
NOTE: When making a second submission please bear in mind that a Similarity Index/Originality Report can take up to 48 hours to appear. You can use the 'Refresh' button within your 'Submissions Inbox' area in Turnitin to refresh your submission to see if your report comes through, although the system will do this periodically.
