Retirement tax questions

SOCIAL SECURITY ADMINISTRATION - Payer's TIN: XX-XXXXXXX.

SSA furnishes its EIN on Form 1099-NEC with respect to social security disability attorney fees paid to attorneys that represent claimants. 

It's not on Form SSA-1099.  Unaware of any reason why a recipient of social security benefits reported on Form SSA-1099 would need the SSA's TIN, which is an Employer Identification Number (EIN), for preparation of the recipient's individual income tax return.
