How can I use multible terraform tf files in one jenkins script?

I am trying to learn terraform usage with jenkins. I realized that I can not use 2 tf files in the same github repository.I have 2 tf files: Providers.tf and Provider2.tf

Provider.tf:

#OpenShot Terraform Project
provider "aws" {
  region  = "eu-west-2"
}

resource "aws_s3_bucket" "b" {
  bucket = "my-tf-test-bucket-leanscale-2"
  acl    = "private"

  tags = {
    Name        = "My bucket"
    Environment = "Dev"
  }
}

data "aws_ami" "ubuntu" {
  most_recent = true

  filter {
    name   = "name"
    values = ["ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-*"]
  }

  filter {a
    name   = "virtualization-type"
    values = ["hvm"]
  }

  owners = ["099720109477"] # Canonical
}


resource "aws_instance" "web" {
  ami           = data.aws_ami.ubuntu.id
  instance_type = "t2.micro"

  tags = {
    Name = "HelloWorld-leanscale-2"
  }
}

Provider2.tf:

#OpenShot Terraform Project
provider "aws" {
  region  = "eu-west-2"
}

resource "aws_s3_bucket" "b2" {
  bucket = "my-tf-test-bucket-leanscale-3"
  acl    = "private"

  tags = {
    Name        = "My bucket2"
    Environment = "Dev"
  }
}

data "aws_ami" "ubuntu2" {
  most_recent = true

  filter {
    name   = "name"
    values = ["ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-*"]
  }

  filter {
    name   = "virtualization-type"
    values = ["hvm"]
  }

  owners = ["099720109477"] # Canonical
}


resource "aws_instance" "web2" {
  ami           = data.aws_ami.ubuntu2.id
  instance_type = "t2.micro"

  tags = {
    Name = "HelloWorld-leanscale-3"
  }
}

Jenkins Script :

pipeline {
    agent any
    tools {
        
        terraform 'terraform-leanscale'
    }
    
      environment {
    TF_WORKSPACE = 'default' //Sets the Terraform Workspace
    TF_IN_AUTOMATION = 'true'
    AWS_ACCESS_KEY_ID = "${params.AWS_ACCESS_KEY_ID}"
    AWS_SECRET_ACCESS_KEY = "${params.AWS_SECRET_ACCESS_KEY}"
    }

    stages {
        stage('Git Checkout') {
            steps {
               git branch: 'staging', credentialsId: 'leanscale', url: 'https://github.com/yusufkaratoprak/leanscale_yusuf.git'
            }
        }
        
        stage('terraform-init') {
            steps {
                sh label: '', script: 'terraform init' 
            }
        }
        
        stage('terraform-apply') {
            steps {
                sh label: '', script: 'terraform apply --auto-approve' 
            }
        }
        
    }
}



```C
[Pipeline] sh

How can OI use multiple tf files in the same repository by Jenkins script?

Move this declaration in its own file instead of duplicating

provider "aws" {
  region  = "eu-west-2"
}

Terraform doesn't care if you use one or 100 files for the code, but definitions must be unique.
