What is the IRS address to file my 2020 amended 1040x if I moved to a different state since then?

The addresses for IRS for people living in PA and CA are different. 

In 2020, I filed in PA but now I am in CA - do I file my 1040x to the same office that looked at my 1040 in 2021? or to the IRS office in my home state now? 

Same as for filing 2018 8606 - I was in a different state back then compared to now. 

Since I want to receive my 2020 refund at the CA address, do I file my 1040x to the CA IRS address instead of PA IRS address that processed my 1040?

You should always put your current address on any tax return you are filing and use the IRS mailing address that matches your current address.  

That way, if the IRS needs to contact you or send you a refund or a letter, the address on the tax return will be correct and not sent to an old address.
