Check your online account with the IRS to see what it says about the stimulus check. Those checks were sent out for 2021, or you could seek the stimulus amount by using the recovery rebate credit on a 2021 return. If you did not receive it, and did not use the recovery rebate credit on a 2021 return, it is --sadly -- too late now.
