Hello.

EC2-Other includes fees for EBS snapshots, etc.
So please check if there are any remaining EBS snapshots.
Delete any remaining EBS snapshots.

You can also see more details by filtering by "Usage Type" as shown in the image below.

Also, If you look at the image, the Elastic IP address remains.
Elastic IP addresses are not free, so we recommend deleting them if you don't need them.

I'll also like to add that you can access any service that may still be running and you're being billed for by going to Billing and Cost Management > Cost Analysis > Cost Explorer. Here, you'll get an overview of what is currently still running and how much has accumulated as a result of each active service.

Note that you can only access this billing information as the root user.

Also, I'll suggest setting up a budget for the account. This you can do by equally visiting ... Billing and Cost Management > Budgets and Planning > Budgets. Then just create a budget, stating the maximum amount you can accommodate in a month. Once you're close to your threshold, you'll definitely get an email to alert you and inform you of any active service and its cost.
