Got a 1099Misc for rental inc from management co., but it shows both 2019 income & some we didn't get until 2020. How do we handle income not rec'd until 2020?

Management company handles collecting rents. They received January's rent (2020) December 31 (2019). We didn't receive it from them until January 7, 2020. Can we delay reporting that amt until the 2020 tax year?
