Rettig is obviously referring to 2020 returns that will be filed in 2021.  As the same newsletter states, 

"Eligible individuals who did not receive an Economic Impact Payment this year -- either the first or the second payment – will be able to claim it when they file their 2020 taxes in 2021."

It helps to read the complete newsletter and not just the misleading quote that someone inserted in the Commissar's mouth.
