I work on my first eth smart contract, and I can't deploy it, the error says: "TypeError: XXXXX.deployed is not a function"

Here is the code for the contract:

//contracts/TestToken.sol
//SPDX-License-Identifier: MIT

pragma solidity ^0.8.17;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/token/ERC20/extensions/ERC20Capped.sol";


contract TestToken is ERC20Capped {

    address payable public owner;
    constructor(uint256 cap) ERC20("TestToken", "TST") ERC20Capped(cap * (10 ** decimals()))
    {  
        owner = payable(msg.sender);
        _mint(owner, 333666999000 * (10 ** decimals()));
    }

    function _mint(address account, uint256 amount) internal virtual override {
        require(ERC20.totalSupply() + amount <= cap(), "ERC20Capped: cap exceeded");
        super._mint(account, amount);
    }

    function destroy() public onlyOwner {
        selfdestruct(owner);
    }

    modifier onlyOwner {
        require(msg.sender == owner, "Only the owner can call this function");
        _;
    }
}`

Here is the deploy.js that gives the error:

const hre = require("hardhat");

async function main() {
  const TestToken = await hre.ethers.getContractFactory("TestToken");
  const testToken = await TestToken.deploy(333666999000);

  await testToken.deployed();

  console.log("Test Token deployed: ", testToken.address);
}

main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});

Terminal error: TypeError: testToken.deployed is not a function at main (C:\Users\XXXX\OneDrive\Desktop\ERC 20\test-token\scripts\deploy.js:7:19) at processTicksAndRejections (node:internal/process/task_queues:95:5)

 Hardhat.config.js:

require("@nomicfoundation/hardhat-toolbox");
require("dotenv").config();

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  solidity: "0.8.17",
  networks: {
    goerli: {
      url: process.env.INFURA_GOERLI_ENDPOINT,
      accounts: [process.env.PRIVATE_KEY]
    }
  }
};

And here is the error:(https://i.sstatic.net/pO9x6.png)

Sorry guys, might be a silly contract, tried for myself for 3 days now, have little to no experience on Solidity, I'm just trying to learn! Thank you!

(My no-skill guess was that I was missing a package but I searched the whole internet and found only a package about it, the hardhat-ethers one and still, didn't work)

Hardhat Version: 2.17.2

Seems like there was a major update to hardhat, try replacing deployed with waitForDeployment()
