excess contributiion 401k

2024 tax year    I discovered that i have an excess contribution to my 401k (changed job in the middle of the year) .  When I told my plan about this (fidelity) they refunded (feb25) the money to me but I don't have a 1099R and they won't issue me one until next year because the refund (dispersal) happened in 2025.  How do I report this?
