Social Security Fairness Act (your article in the January 5th,2024 Chicago Tribune)

I am a retired 75 year old federal employee currently receiving a CSRS annual pension of $136,000. I retired with 45 years of service from April 1972 to October 2017. I had 23 quarterly Social Security credits prior to my federal retirement. Upon my federal retirement, I have been working a part time job earning Social Security credits. I have received a letter from Social Security indicating that I have 40 quarterly credits and am eligible for benefits. I never applied for Social Security benefits because I assumed that I would not be eligible because of WEP and GPO. Under the provisions of the Social Security Fairness Act, am I now eligible to receive Social Security benefits? Should I now apply for Social Security benefits?
