My employer withheld more SS Tax than was needed by about $5000 for 2018. I contacted them when I saw this - in Mar 2019. They sent back a corrected W2 but said I need to collect my refund from the government since they had already transferred funds to the government. So my question is as follows: I thought the employer was supposed to issue the refund before sending me a corrected W2. Since they did not issue a refund, should I used the old or the corrected W2 on my return? My worry is if I used the corrected W-2, then how do I show that more SS tax was collected and that employer did not actually issue the refund?
