Change the resource id of the transit gateway fails, apply again and it works:

$ cat main.tf
variable "ibmcloud_api_key" {
}
variable "resource_group_name" {
  default = "default"
}
variable "region" {
  default = "us-south"
}

variable "basename" {
  description = "Name for the VPC to create and prefix to use for all other resources."
  default     = "example"
}

provider "ibm" {
  region           = var.region
  ibmcloud_api_key = var.ibmcloud_api_key
  generation       = 2
}

data "ibm_resource_group" "group" {
  name = var.resource_group_name
}

#resource "ibm_tg_gateway" "tgw2"{
resource "ibm_tg_gateway" "tgw"{
  name              = "${var.basename}-tgw"
  location          = var.region
  global            = false
  resource_group    = data.ibm_resource_group.group.id
} 
$ terraform apply -auto-approve
$ edit main.tf
