As a new seller the message was correct that your payment will be held by eBay as a security precaution for up to 30 days, shorter if you upload the tracking number and the item is recorded as delivered.
If the buyer has paid you will receive a separate message from eBay to confirm this, and inform you that the item can now be dispatched to the buyer. Don't do so until you receive this, and have taken advice as below.
