An ERC20 contract takes four arguments in the constructor. My constructor is defined like this:

  string public name;
  string public symbol;
  address public admin; // For debugging
  uint8 public decimals;
  uint256 public totalSupply;
  event Deployed(address indexed _admin, uint256 indexed _totalSupply, string _name); // For debugging

  constructor(string memory _tokenName, string memory _tokenSymbol, uint8 _decimals, uint256 _initialSupply) public {
    name = _tokenName;
    symbol = _tokenSymbol;
    decimals = _decimals;
    totalSupply = _initialSupply;

    admin = msg.sender; // For debugging
    balanceOf[msg.sender] = totalSupply;

    emit Deployed(msg.sender, totalSupply, _tokenName); // For debugging
  }

I use this JavaScript code to deploy an ERC20 contract to my private test net.

var contractObject = web3.eth.contract(<ABI definition>);
var submittedContract = contractObject.new('DKK', 'DKK', 1, 1000000,  {data:'<bin>', gas: 20000000}, <callback>);

Calling eth.getTransactionReceipt(submittedContract.transactionHash); returns (only relevant fields included):

eth.getTransactionReceipt("0xeb512f29ef2789b592b19acbbb78f8c6be6f7eaed96460c239e0a5d8c20e1dd2");
{
  contractAddress: "0xe23cfc0248b83a4bce8f9701a86e08e9cf9c59f4",
  ...
  logs: [{
      ...
      data: "0x00000000000000000000000000000000000000000000000000000000000000200000000000000000000000000000000000000000000000000000000000000003444b4b0000000000000000000000000000000000000000000000000000000000",
      ...
      topics: ["0xf0bbe877a87290e236ea898bbce0d78d6ac7d54d62e32744b129798a2669e39b", "0x00000000000000000000000075bf9b4280b7963ddb1e9198b3aca5b1e02dcf57", "0x00000000000000000000000000000000000000000000000000000000000f4240"],
      ...
  }],
  status: "0x1",
...
}

The status field should indicate that there were no errors, but I am not sure that my constructor values are set correctly. Can you see that from the topics field?

When I then call contractObject.at("0xe23cfc0248b83a4bce8f9701a86e08e9cf9c59f4").totalSupply();, it returns 0. But it should return 1000000.

Following my comments above, try this:

async function test() {
    var contractObject = web3.eth.contract(...);
    var submittedContract = await contractObject.new(...);
    var totalSupply = await contractObject.at(...).totalSupply();
    console.log(totalSupply);
}

test();
