I sell products online through Etsy. TurboTax and Etsy are telling me different things regarding receiving a 1099K Form.

TurboTax is telling me I will receive a form if i sell more than $600. Etsy is telling me they will only send a 1099K form if I sold over $20,000.. Which is correct? If i do not have a form can i still enter my own income/expenses?
