Why does my benefit statement say that I was paid 9,450 in 2016 for 2014 and paid 5,250 in 2016 for 2013? Where did those amounts come from?
I don't know, but sometimes Social Security pays retroactive benefits that date back for a number of years. This can happen for a number of reasons, such as a successful appeal, or a refund of benefits previously withheld due to the earnings test, etc. You would need to check with Social Security for an explanation.
