You might want to discover the aws services that are the dependant of this services, we can use a simple bash script for the discovery instead of blindly scrolling the aws console.
#!/bin/bash
vpc="vpc-xxxxxxxxxx"
myregion="us-west-2"
aws ec2 describe-internet-gateways --region $myregion --filters 'Name=attachment.vpc-id,Values='$vpc | grep InternetGatewayId
aws ec2 describe-subnets --region $myregion --filters 'Name=vpc-id,Values='$vpc | grep SubnetId
aws ec2 describe-route-tables --region $myregion --filters 'Name=vpc-id,Values='$vpc | grep RouteTableId
aws ec2 describe-network-acls --region $myregion --filters 'Name=vpc-id,Values='$vpc | grep NetworkAclId
aws ec2 describe-vpc-peering-connections --region $myregion --filters 'Name=requester-vpc-info.vpc-id,Values='$vpc | grep VpcPeeringConnectionId
aws ec2 describe-vpc-endpoints --region $myregion --filters 'Name=vpc-id,Values='$vpc | grep VpcEndpointId
aws ec2 describe-nat-gateways --region $myregion --filter 'Name=vpc-id,Values='$vpc | grep NatGatewayId
aws ec2 describe-security-groups --region $myregion --filters 'Name=vpc-id,Values='$vpc | grep GroupId
aws ec2 describe-instances --region $myregion --filters 'Name=vpc-id,Values='$vpc | grep InstanceId
aws ec2 describe-vpn-connections --region $myregion --filters 'Name=vpc-id,Values='$vpc | grep VpnConnectionId
aws ec2 describe-vpn-gateways --region $myregion --filters 'Name=attachment.vpc-id,Values='$vpc | grep VpnGatewayId
aws ec2 describe-network-interfaces --region $myregion --filters 'Name=vpc-id,Values='$vpc | grep NetworkInterfaceId
And you should get the output of all the depending services, and you can easily delete them and rerun the terraform destroy command
