IRS has held my tax refund for 2021. I got the notice (CP05A) . 'Statement of benefits on retirement income....' How do I get it? Please provide contact and online links.

Sounds like they want a copy of the 1099-R that you entered onto the return.

What this notice is about

What you need to do

• Send us copies of the items listed on the notice so we can verify your income and income tax withholding.

  • Mailing your response to the address shown on the stub.

Thanks for the input Critter.

I checked my return, I have not added any 1099-R forms. In that case, what should I do?

Did you call the number on the notice and ask them how to handle this issue of a missing form?   

Read the notice again carefully ... did they just  give a generic list of things to possibly send ?   If so send what you have ... read the info in the link I posted for IRS direct instructions. 

Thanks Critter. They have asked for my salary slips and letter from Employer. I will just provide them.

Appreciate your help.
