Hello.

The charges shown on your bill are for EBS volumes.
You may have created an EBS volume in the Stockholm region with a size that exceeds the free tier limit.
Change the region to Stockholm in the management console and check the EBS volume screen to see if any unnecessary volumes remain.
You can check the global view from the URL below to see if any volumes remain.
https://us-east-1.console.aws.amazon.com/ec2globalview/home?region=us-east-1#

If there are no volumes left, it should say "0 in 0 regions" as shown in the image below.

You can change the region of the management console by following the steps in the document below.
