It is unfortunate there isn't a thumbs down button because all of the information you gave me is incorrect. If it was a single employer the employer would reimburse me. For multiple employers the form 843 is used to request those overpaid taxes back. As I stated, I payed railroad retirement taxes, I do not pay into social security. Turbo tax does not put excess railroad retirement taxes back into the amount due and even notified me of the need to file an 843 to have the excess returned to me. My question was not whether or not I needed the 843, but where and how to file it. I only responded to this "answer" to my question so others would not be mislead.
