Where can I find a breakdown of the fees charged on a sold item?

[fromearthandfiredesigns]

I am trying to find a breakdown or explanation of the fees taken out of an item I just sold in March. It seems like they took more out than usual. There isn't a recent invoice available under my seller account. The most recent they have available is from January. How the hell do I get a break down of the fees on an item I just sold?!
Thanks!
