Turbo Lister no longer supported after June 2017
As all key Turbo Lister functionality will be made available in Seller Hub, eBay will discontinue support for Turbo Lister after June 2017. Seller Hub already enables you to create professional, quality listings, and upload and manage listings in bulk. More improvements to Seller Hub’s listing process are coming soon, with a focus on addressing seller feedback and adding capabilities for sellers who use Turbo Lister today. Send your feedback on Seller Hub listings capabilities to DL-eBay-SH-Listings-Feedback@ebay.com.
The above is from the Fall update. I have a feeling many of things I use it for are not a priority for Ebay (ie, archiving listings, moving listings between IDs etc.)
Hopefully something comes along to replace it but not holding breath.
