@glenbankloel,

Do you mean order details as a buyer?

If so, then bear in mind that eBay only keeps a record of your purchases over the last 3 years. (2019 doesn't make the cut, I'm afraid.)

The default view in your Purchase History (under My eBay) shows transactions from the last 60 days.

To change the date range, click onto the caret and select the appropriate date range from the drop-down menu:

If you mean as a seller, I suppose you would go to Seller Hub, and view your orders - customising the period. Or... would it be in Reports (downloads) in Seller Hub? That's all I could suggest...
