Extract subnet id's based on subnet name in virgina region

Question

I need to extract the subnet ids by passing the subnet names and get the output of the subnet ids.

main.tf

module "data" {
    source      =   "./data"

}

output "subnetid" {
  description = "The current bid status of the Spot Instance Request"
  value       = module.data.subnetid
}

Module data folder.

data.tf

data "aws_vpc" "vpc-id" {
  filter {
    name   = "tag:Name"
    values = ["kdt-vpc"]
  }

}

data "aws_subnets" "selected" {
  filter {
    name   = "vpc-id"
    values = [data.aws_vpc.vpc-id.id]
  }
  filter {
    name   = "tag:Name"
    values = ["kdt-private-subnet-0","kdt-private-subnet-1"] # insert values here
  }
}

outputs.tf

output "subnetid" {
  description = "The current bid status of the Spot Instance Request"
  value       = data.aws_subnets.selected.id
}

When I run the terraform apply I am getting the output as

Changes to Outputs:

• subnetid = "us-east-1"

How Can I get the correct subnet id's by passing the two subnet names
