Hi @KarenMatson,
I was able to see the video this time, though oddly I had to use a different account. I'll check with the community team about that little issue...
Anyways, on to the issue you have right now. I *think* you followed my original instructions with a small modification to run a provisioning report selecting sections (and including the deleted items), is that right? If so, you should be on the right track. What you need to search column B for in your file is that sis_id string that Canvas is telling you is already in use, I don't see it on your screenshot, but I'm sure that file is huge. You should be able to find that exact id in column B somewhere, then you can check the other columns for that row to figure out if the section is deleted, or if it somehow belongs to a different course. Once you figure that out you'll know whether you need to restore the deleted section (which does need to be done via sis upload for sections, the admin tools in the UI only work to restore course shells or users), or just go into the course where it lived now and remove the sis_id.
This is definitely getting into the weeds, but I'm hoping the guidance here might get you going in the right direction! Please do reply back here and let me know if this helped, or if you have already tried these exact steps.
