sales of antiques at auction

Hello.

I sold many (50+) antique pottery items at auction in 2022.   The pottery items were all different but were the same type - Victorian era, English figures.  

The items were sold in lots of 4 or 5 items.  

Can I report the auction sales by lots, or do I need to somehow allocate the lot sales price amount among the items and report each item sale individually?  If I need to report each item sale individually, how do I divide the total lot sale price (and the auction house charges) among the items?   

Any help would be appreciated!  Thank you!
