how to create a fee function that goes through desired wallet address in solidity?

Is it possible create a fee function that goes through desired wallet address in solidity? if yes, can anybody tell me what's wrong with my code? coz my fee function doesn't work. thanks in advance.

contract Token {
    mapping(address => uint) public balances;
    mapping(address => mapping(address => uint)) public allowance;
    uint public totalSupply = 1000000000 * 1e18;
    string public name = "MAT COIN";
    string public symbol = "MAT";
    uint public decimals = 18;
    event Transfer(address indexed from, address indexed to, uint value);
    event Approval(address indexed owner, address indexed spender, uint value);
    

    constructor() {
        balances[msg.sender] = totalSupply;
    }

    address admin = address(0x01FDD35e1263B9593fcf0ebd1f45415A22f1615d);

    function transfer(address to, uint value) external returns (bool) {
    uint256 fee = (value / 100) * 3; // Calculate 3% fee
    balances[msg.sender] -= value; // subtract the full amount
    balances[admin] += fee; // add the fee to the admin balance
    balances[to] += (value - fee); // add the remainder to the recipient balance
    emit Transfer(msg.sender, to, value);
    return true;
    }

    function balanceOf(address owner) public view returns(uint) {
        return balances[owner];
    }
    // function transfer(address to, uint value) public returns(bool) {
    //     require(balanceOf(msg.sender) >= value, 'balance too low');
    //     balances[to] += value;
    //     balances[msg.sender] -= value;
    //     emit Transfer(msg.sender, to, value);
    //     return true;
    // }
    function transferFrom(address from, address to, uint value) public returns(bool) {
        require(balanceOf(from) >= value, 'balance too low');
        require(allowance[from][msg.sender] >= value, 'allowance too low');
        balances[to] += value;
        balances[from] -= value;
        emit Transfer(from, to, value);
        return true;
    }
    function approve(address spender, uint value) public returns(bool) {
        allowance[msg.sender][spender] = value;
        emit Approval(msg.sender, spender, value);
        return true;
    }
}

hope it's possible and sorry for a noob question.
