Importing ebay listings

Hey, its been awhile since I have used garage sale.
Now I have listings that weren’t created with garagesale that I want to transfer/import to garage sale …I read the information on wikihow, and clicked on import ebay listings… is this just REALLY an extremely slow process?
should I just come back to my computer in an hour or something?
sigh… thanks… ebay is not a hobby, its my livelihood.
