confused on taxes help needed badly

 

Hi  I have a two part question, and I thank anyone in advance for help on this.  In Jan 2021 I received a letter from the IRS about an amount I claimed on my 1040 it is an amount that I get from my husbands pension - he pays by check each month and for the last 10 years I have been claiming it as a pension,  I get no paperwork on this so I just put it in that area as Income.  this year they sent me a letter to clarify where I get this money.  I faxed a letter and a copy of my divorce decree to them on Feb one and still have no response.  they have on my transcript page that I didn't do my 2019 taxes, yet they have my canceled check for proof.  I call twice a week

and no one answer my question.

2nd question - I received SSI for the last month of 2020 but have received no 1099 to show proof of this income - and there is no 1099 on my account page,  I want to file 2020 but I dont know how to prove I got that money for the last month Dec of 2020

 

I am beyond frustrated tried to contact them several times with no luck   any help would be so much help

I thank you in advance  PKS
