I already called them and argued that since the check was not cut until 2018, the1099 should not be issued until the end of 2018. They said that they processed the transaction on December 29, 2017 so that's when they reported it. I argued that just because they entered a process doesn't make it a payment. It's not a payment until the check is cut. The check was not cut until 2018 and, therefore, was not income received by me in 2017. I had no access to the money until 2018. They refuse to correct it.
