Ask Social Security Questions and Get Answers ASAP
You will need to contact the social security office directly about this matter. While there is the possibility that they will transfer your earnings, there is a greater possibility that since you were using a social security number that did not belong to you, they may not transfer the earnings.

Let sleeping dogs lie, unless you want to open up a can of worms for yourself.
