After you file

I won’t owe for 2020. There will be a refund amount but it will be taken to offset my outstanding tax debt from 2016 I’m sure like 2017, 2018, and 2019 were.  

Let’s say my 2020 refund is 750 and I claim my recovery rebate credit for 600. 750 will be taken for my 2016 tax debt and and I will receive 600? Is that your understanding? Thanks.
