In most late-payment situations, you can call the bank and ask them to forgive the late fee as most banks don’t report immediately.
If it hit your credit, it probably sat more than 30 days and a late-fee forgiveness call isn’t going to help at this point.
Once it’s reported to the bureaus, getting it removed is a much more involved process.
You can try to implore the bank to remove it but it’s not likely to happen given how long you allowed the late payment to remain.
This will probably just be a “lesson learned” and will need to go through the time process to eventually drop off.
