Should I deposit unexpected 2022 Refund check IRS sent

Greetings:

 

IRS  sent a unexpected refund check for 2022 that I received today.  I am yet to receive any notice with explanation.

 

I am assuming that it is  Estimated 2022 taxes applied from refund due from 2021 original return. 

 

1. In my Original 2021 return in Line 36 of 1040 I chose to have X amount of refund to be applied to 2022 Estimated taxes.

2.  In 2021 Amendment that I filed in January 2023  I owed additional tax amount Y but was still due a refund. I did not choose to take refund but in Line 23 of 1040-X reduced the 2022 Estimated taxes applied to X minus Y.  

3. The 2021 amendment is yet to be processed as IRS is taking up to 20 weeks.

4. I filed my 2022 return timely without extension and indicated in line 26 of 1040 that I have Paid Estimated tax of X minus Y .

 

Today I received refund check for Y dollars so it seems that IRS processed the 2022 return and updated the line 26 of 2022 1040 on its own to X instead of Y.  

 

I am yet to receive a notice why this refund was issued.

 

Should I deposit this check for Y dollars ?

If so I think I will owe Y dollars when IRS ends up processioning my 2021 Amendment and realizes that they have refunded me Y dollars from 2022 account.

 

Any advise so I do not complicate this further !!

 

Thanks Regards
