Overcontributed to 401(k) in 2018. I alerted the plan administrator and they sent me a check but for a different amount. How do I enter this?

I changed jobs in 2018 and accidentally over-contributed to my 401(k) by $111. I alerted my plan administrator prior to filing taxes, and they sent me a check for $99, but no 1099R.

How do I go about entering this into TurboTax? Do I fill it out under miscellaneous income, or do I fill it out under Retirement Plan income? What do I put in the boxes if under Retirement Plan (111 or 99)?
