We have many RDS instances in our AWS account which we are not sure where they are getting used. We can see some active connections in some cases and wanted to find the source of those.

You could use VPC Flow Logs - Amazon Virtual Private Cloud on the Subnet containing the RDS DB instance.
Flow Logs can show the source/destination of traffic in the Subnet, and you could then figure out which EC2 instance has the source IP address.
