My W2 says I overcontributed to my TSP Roth IRA. I did not over contribute though and my leave and earnings statements and TSP records both show I did not overcontribute. How do I correct this? Can I enter the correct amount in box 12 of my W2 in Turbo Tax? I cannot figure out who I am supposed to contact as I am no longer active duty military and the finance office says they do not issue W2s. I don't see an option to enter a W-2 C and I don't have one anyways. Not sure how to proceed.
