The only documents that you need to send are the ones that show the tax withholdings. So, according to the information you shared, you should send copies of your SSA-1099 forms that show the voluntary Federal tax withheld from your Social Security payments.
Do not send your original documents. You should keep those and send a copy to the IRS.
The letter should give you the address for where to send the SSA-1099 to the IRS.
