Missing Money After Crypto Sale, "chargeback processed" from months ago.

I just sold some crytpocurrency. My fiat balance is missing several hundred dollars. When I look at my banking history I see "chargeback processed" from several months ago that matches the amount perfectly. However, there is no record of the funds going anywhere TODAY. I cannot account for this several hundred dollars suddenly missing. What happened? Can anyone explain why my bank would say "chargeback processed" months ago but take the money today, perhaps? And if so, would I see that money show up on my bank account today at some point?
