A friend sent me money using Venmo and accidently marked it as goods/services. Venmo refunded the fee but can not reverse transaction. I will get a 1099-k now. Now what?

I also sent my friend the money back so it looks like a return/refund, since Venmo can not reverse the transaction. I have no history of goods/services transactions. This is the first one. When I get this 1099-K should I ignore it or file it? If I do file it, how do I deal with something like this?
