Do I have to use Ebays Labels for postage?

[ful213254]

I have sold my first item on Ebay and I said on the listing that postage would be on me rather than the customer. Now when I go to ship, I have a page that wants me to input stuff for a label that I don't really know what to put in. I had been to the Post Office before I listed the item and I know what I need to post the item and how much it will cost, so can I just go to the Post Office and post it or do I need to do this Ebay Label stuff?

I did find a page which allowed me to just input carrier and tracking number. If I post it myself, is this all that I need to fill out?

You don't have to use eBay labels, just use AP but you MUST make sure you upload the tracking to the sale and post over the counter at the post office to get a tracking event.

Also take out insurance if it's the collectable cards.
