Low-level user, need help with TLS 1.2 update

Hello! Please be compassionate - I'm an extremely low-level AWS S3 user (zero tech knowledge other than how to create and add to my buckets for nonprofit training programs). I have apparently ONE bucket that needs to be updated to TLS 1.2 compliance. I have read and followed the how-to instructions in the email and am .... overwhelmed. Steep learning curve to update one bucket! Can anyone help with SUPER SIMPLE STEP BY STEP GUIDANCE on this update? Or want to do it for me? Here's what the notification email lists for my affected bucket:

Please see the following for S3 buckets in which object-level calls were made over TLS 1.0 or TLS 1.1 connections between July 17, 2023 and July 25, 2023 (the UserAgent may be truncated due to a limit in the number of characters that can be displayed):

Connections details will be in the following format: Region | Bucket name(s) | APIAction | TLSVersion | NumCalls | UserAgent us-west-2 | blueprint-training | REST.GET.BUCKET | TLSv1 | 1 | []

I would be so grateful for your help in getting this taken care of - thank you!
