TRC20 are actually smart contracts. tronscan USDT link To transfer TRC20 from your address to another address, you will be calling TRC20's transfer function, below is a snippet of Tron USDT's code.

function transfer(address _to, uint256 _value) public returns (bool) {
    require(_to != address(0));
    require(_value <= balances[msg.sender]);

    // SafeMath.sub will throw if there is not enough balance.
    balances[msg.sender] = balances[msg.sender].sub(_value);
    balances[_to] = balances[_to].add(_value);
    Transfer(msg.sender, _to, _value);
    return true;
  }

TronWeb TRC20 Contract Interaction documentation. You can use tronWeb's triggerSmartContract function to create a raw transaction, sign and broadcast.

create raw transaction

var senderAddress = tronweb.defaultAddress.base58;
var receiverAddress = "TV3nb5HYFe2xBEmyb3ETe93UGkjAhWyzrs"; 
var amount = 100;
var parameter = [{type:'address',value:receiverAddress},{type:'uint256',value:amount}]
var options = {
  feeLimit:100000000                    
}

const transactionObject = await tronWeb.transactionBuilder.triggerSmartContract(
    tronweb.address.toHex(contractAddress), 
    "transfer(address,uint256)", 
    options, 
    parameter,
    tronweb.address.toHex(senderAddress)
);

Note: address are all in base58 format, we need to convert it to hex format using tronweb.address.toHex(address) at transactionObject. The parameter variable is where we set the receiver address and amount.

Sign

var signedTransaction = await tronWeb.trx.sign(transactionObject.transaction);

Broadcast

var broadcastTransaction = await tronWeb.trx.sendRawTransaction(signedTransaction);
console.log(broadcastTransaction);
