In-use public IPv4 address per hour billing in my Free Tier

Question

I have an AWS Free tier account and I see that I have been billed for In-use public IPv4 address per hour for 54.814 Hrs.

I do not have any EC2 instances, ALB, Elastic IPs in my account. 
(An ALB was active which I stopped 12hours ago)
The only thing that I have is default VPC and the subnets. I also checked in IPAM Public IP insights, it shows "No Public IPs found" I am not sure how to stop this being billed further. Please guide.

Thank You![Enter image description here](/media/postImages/original/IMk1fygT5ASJCNkwyxMFLCUw)

Answer

If you go to Cost Explorer, filter "PublicIPv4" under UsageType, do you see anything related to PublicIPv4:InUseAddress or PublicIPv4:IdleAddress?

Answer

Yes. I see PublicIPv4:InUseAddress in cost explorer.
I stopped all my EC2 instances and it is well within the 750hours range. I am not sure where this public IP is.

Also please clarify below
1) Do I incur charges for public IPv4 if an EC2 instance is running (below the 750 hours ) in free tier
2) Do I incur the public IPV4 charges for creating a Load balancer (just creating and keeping it active with no underlying EC2)
3) Do I incur the public IPV4 charges for default VPC and subnet?
