How report 2020 Cares Act Payment Received When Married, Now Divorced Filing Single

In April 2020 my wife and I we received a first round Cares Act payment for $1677.45, we did not receive a second round payment.  In 2019 we filed a joint return with status married. We divorced in August 2020 and we are filing single in 2020. How do we report the stimulus payment on our separate returns?
