TP received a letter from the IRS after his e-filing.  The IRS letter had Estonia prepaid postage and was dated October 21, 2019.  Is this a real IRS letter from Estonia?  Let me give you some facts as follows:

1. TP resided overseas and printed his foreign address on page 1 of his 2018 Form 1040.

2. As per PTO, TP’s return was accepted by the agency on October 4, 2019.

3. TP is expecting a refund from his filing of Form 1040 (less than $2,000 refund).

4. The upper right hand corner of the letter from the IRS had letter number, letter date and tax period.

5. The IRS letter is requesting the following information:

a) A copy of pages 1 and 2 of the return,

b) Amounts and dates of all estimated tax payments paid this year,

c) Any supporting documents verifying income or withholding,

d) A copy of the IRS letter itself.

e) All the requested information should be mailed to Internal Revenue Service, Austin Submission Processing Campus, 3651 S IH 35, Austin, TX 78741, Mail Stop 6126 AUSC.

f) TP’s contact number and hours he can be reached.

As I never receive a letter from IRS with a prepaid Estonia stamp, I just want to make sure this is legitimate.  Item being requested such as page 2 of 2018 Form 1040 is not in existence.  They should have a complete copy of Form 1040 but requested pages 1 and 2 of the return.  Can I have any of your comment?  Thanks a lot.
