Paid for vacation time that i had to pay back

I left my job in may 2018 and was told I was overpaid for vacation time. I paid the amount of around $1,200 back in 2019. 

1. Am I going to get a w-2c for this

2. If I'm currently getting a tax return and will not owe in do I need to add it.

         A. Would it just add to my current refund or not even change it since the taxes paid back were fairly low.
