Which Revision To Use
Use the July 2021 revision of Form 1040-X to amend 2019 and
later tax returns, until a later revision is issued. Use these
instructions with the July 2021 revision of Form 1040-X.
If you are amending a 2018 or earlier tax return, use the prior
revision of this form and instructions both dated January 2020.
All revisions are available at

IRS.gov/Form1040X.

I think you can find your answers in the above.

Just curious, why are you filing older returns. You can't claim refund over 3 years. If you are filing because of irs letter you should call number on letter and ask that question.

Could be 2019 NOL carryback.

Could be 2019 that is not yet paid. It can be filed within 2 years of the date you paid the tax.

Good afternoon,

I was actually trying to locate where to send the amended tax returns, after they are finished filed.  I located an address in Austin, Texas, as my client lives in Florida like me.

When all else fails READ THE INSTRUCTIONS the address is on page 9 https://www.irs.gov/pub/irs-pdf/i1040x.pdf
