Ok, after about 45 minutes of searching, I was able to get back to the old "My eBay" page:
1. click on "My eBay" and use the drop-down menu to select "summary".
2. At the bottom of the "summary page" there is a link under "selling activity" that says: "Looking for your selling activity? Go To ALL SELLING to access your listings and sales!"
3. Click on "ALL SELLING" and then you can use the menu on the left-hand side to get back to your sold items, etc...
