My items were showing in ENDED as UNSOLD but not showing in unsold or awaiting payment.
I found this old Post that worked for me.
Found an old Post solution that worked for me
"Seems what helps is:
1. go to the list of Ended items
2. Click on those miscategorized items
3. Click on Bids links to go to bids history
4. Refresh that page
In the Action column the link "Send Invoice" will get added and now the item will be correctly listed in Awaiting payment list." I had to REFRESH several times to get it to show Send Invoice. Then you can either send invoice right there or go to Awaiting Payment to send invoice or do whatever you need to.
