Retirement tax questions

I finally wrote a letter to my congress rep. They got in touch with an advocate who never bothered to contact me. She wrote them back a letter that said I had never filed... which I DID and I have confirmation it was received on 8/5/20. I was instructed to file again... which I will. I'm sending it priority mail so I have proof that it was delivered. If I don't get a response in 3 weeks I'm supposed to contact the advocate directly... SO all that said. 

Write to the highest level in the Gov that you can.
