Hello 2MuchStuff -
There is a free tool available
HERE that you can paste your item number into and it will scan your listings for issues relating to eBay compliance and secure links are part of that scan. The Markup tab on this tool will show you what and where the link is once your item has been scanned. As long as the item is still eligible for revision on eBay, you can then make any changes to the listing that you might need to make.
Alternately, please feel free to file a support case from under the Help tab of the site letting us know what you've run into and the item number involved and our support team will be happy to take a look into it for you.
