When your client purchased the product, Etsy included the whole $14.11 as your sale, therefore you should include the whole $14.11 as a return.
The amount that Etsy took for handling the return, can be included in the fees you are paying Etsy to manage your transactions.
Feel free to reach back if you have any additional questions.
Thank you for your reply! I was actually refunded $0.67 by Etsy for the processing fee. This is the breakdown:
$0.67 of your payment processing fee was refunded by Etsy.
$13.44 was charged to your MasterCard
totaling $14.11
I wanted to make sure i'd still be putting the whole $14.11 even in this instance. Thanks again
