Hello @Withrow505 and welcome to the forums.
So, it sounds like your payment was past due for ~60 days? My understanding is that usually notifications are sent to an individual's inbox and/or text alerts whenever any balance or minimum payment is due. Although, there have been mixed outcomes when dealing sith SYNCB in removing late payments, but you can always try and see if any GW letters would work.
Unfortunately an "honest mistake" won't always be considered by a creditor. They are not your friend willing to take that into account, regardless of your payment history. Most lenders don't care about your history once you're late and an honest mistake can hurt you for 7 years. If you find one that easily removes it let us know.
Usually the best you can do is plead you case and often numerous times. There's the goodwill (GW) campaign that most say will usually take numerous pleads to get removed (if removed) and you have to be diligent and deliberate in your efforts but the forum shows its been successful for many. Search "Goodwill" and you may find your creditor with specific contact information or the best way that will help your efforts. Good luck!
