Do I need to pay taxes in the US for a piece of land I sold in Argentina for $10,000 with my only record being a wire transfer to my US bank account? If so, how?

I sold a piece of land. I got the payment in my US bank account and I don't have any paper trail. I was told I need to pay taxes but couldn't find a way to do in on Turbo Tax without having any type of forms (W-2, 1099-MISC, etc.)
