Here is my javascript code: The address I'm sending it to is input address from user on app. The caller (currently selected metamask address has enough ERC20 tokens)

lookupVoterInfo: function() {
   let toAddress = $("#voter-info").val();
   Voting.deployed().then(function(contractInstance) {
     contractInstance.transfer(toAddress, 10);
   })

MyERC20 Contract:

pragma solidity ^0.7.0;

import "../openzeppelin-contracts/contracts/token/ERC20/ERC20.sol";

contract MyERC20 is ERC20 {
    uint256 public INITIAL_SUPPLY = 20000;
constructor() ERC20("MyToken", "MYT") {
        _mint(msg.sender, INITIAL_SUPPLY);
    }
}
