Once you upload a listing, it may take up to 24 hours to "index" and show on the site.
A new seller like yourself should plan to wait the full 24 hours, as should occasional sellers, and sellers in high value/high fraud categories.
Meanwhile, have you set up a method allowing eBay to transfer customer payments to your bank account?
You need a checking account in a US bank plus acceptable identification.
Note that your bank identification must match your eBay identification exactly.
If your name is John Jacob Jingleheimer Smith, you cannot have a bank account as John Jacob Jingleheimer Smith, a Managed Payment account as J J Jingleheimer Smith, and an eBay account as JJJ Smith.
