I think you may be prevented from listing an item, because you have not fully or correctly registered with eBay's Managed Payments.
You need to provide eBay with details of a bank account and have this account verified. The usual method here, is for eBay to send 2 micro deposits into that nominated bank account for you to receive, and confirm to eBay.
Once this is completed, you will be able to list items for sale, and receive payouts from those sales.
This will show you how to register for eBay's Managed Payments.

If there is an issue with the registration contact eBay Customer Services, who have full access to your account, and can see where the issue lies and explain the steps you now need to take.
If you couldn't reach Customer Services before their lines open later on weekends at 9 a.m. so they're open now, however I'm sure registering for Managed Payments is the issue here , once registered you'll be all set to sell.
If you do need to reach Customer Services, the easiest and quickest way to contact Customer Services is through this link, for a Call Back .

On weekdays lines open between 8 a.m. and 10 p.m. - 6 p.m.
Weekends lines open between 9 a.m. to 6p.m.
I would also recommend waiting until tomorrow morning and contact them very first thing at 8 a.m. when the lines first open, as there's more chance of Dublin answering.
