2021 Stimulus

Hello!

For my child my ex husband and I claim our son every other year.  He claimed him in 2019 therefore, he got the stimulus in 2020.  I claimed him in 2020 so I should have received the stimulus payment given in 2021. But that was not the case, I did not get his stimulus.  Will I be able to claim this on my 2021 taxes?

Thank you!
