Years ago the Social Security Administration would send you a statement just prior to your birthday each year.  Those days are long gone and you'll need to set up an account to view your benefits

Here's the link: Social Security

 Once you've logged in you'll be able to view your estimated social security benefits available at age 62, full retirement age and age 70.  You'll also be able to see your annual earnings record and how much you've paid  in Social Security and Medicare taxes during your career.
