I am due the second stimulus and I’m on a IRS payment plan. If I claim the rebate credit will it be taken with the rest of my 2020 refund?

I’ve been on a payment plan for my 2016 taxes. I pay monthly and my refunds since have been used to offset. I got the first stimulus. I have not received the second. I’m assuming the worst and assuming the irs made an error and I won’t get it. I know the stimulus is not to be seized to offset tax debt. However, if I claim the rebate credit on my 2020 return for the missed 2nd stimulus, won’t that be taken to offset my tax debt along with the rest of my 2020 return?
