Hello Donabelle OronosWelcome to the Canvas Community. Thank you for posting your question. Assuming that your instructor has set up the app integration between Canvas and Turnitin correctly (so that you see the Turnitin interface right within a Canvas assignment), there are a number of videos that have been created that show how assignments can be submitted. I'm going to provide a few of these links, but keep in mind the interface may have changed slightly compared to what the videos show. The process should generally be the same, though.
