@Opus 17 - I'm in the same exact situation as the first person on the thread. I accepted a sign-on bonus in 2018 (well over $3K), but then left the company and repaid the full bonus back in 2019. I received a W2C for 2018, but box 1 did not change. Only the social security and medicare wages were updated.
I spoke to "experts" at TurboTax twice, but I'm still not 100% convinced I got the right advice. They advised me to amend my 2018 return. Since box 1 was not updated, they told me to simply subtract the bonus amount from the original wages reported for 2018 and then enter the new amounts for the SS and medicare wages.
Does this sound correct?
Thank you in advance.
