Storing variables that hold an element from a file into a variable

Okay, so im reading from a file and than splitting and storing the elements into different variables. enter image description here

I have a class called Person and im trying to store this info into a person object such as people.Add(new Person(firstName, lastName, address)); This works fine except for the address i cant seem to figure out. You see, i have a class called Address as well which holds street, city, state, etc. I can't seem to figure out how to store the address variables i have that are loaded with the info from the file to a new variable to add to the person object. Here is some code

PERSON CLASS

internal class Person : IComparable<Person>
    {
        public string FirstName { get; init; }
        public string LastName { get; init; }
        public Address Address { get; init; }
        
        //constructor
        public Person(string firstName, string lastName, Address address)
        {
            FirstName = firstName;
            LastName = lastName;
            Address = address;
        }
    }

ADDRESS CLASS

 internal class Address
    {
        public string StreetAddress { get; init; }
        public string City { get; init; }
        public string State { get; init; }
        public string PostalCode { get; init; }

        //constructor
        public Address(string streetAddress, string city, string state, string postalCode)
        {
            StreetAddress = streetAddress;
            City = city;
            State = state;
            PostalCode = postalCode;
        }
    }

PROGRAM

string root = FileRoot.Root;

string csvFile = root + Path.DirectorySeparatorChar + "data.csv";

string psvFile = root + Path.DirectorySeparatorChar + "data.psv";

List<Person> people = new List<Person>();

using (StreamReader sr = new StreamReader(csvFile))
{
    while (!sr.EndOfStream)
    {
        string line = sr.ReadLine();
        Console.WriteLine(line);
        var split = line.Split(",");

        // get and store info from file
        var firstName = split[0];
        var lastName = split[1];
        var streetAddress = split[2];
        var city = split[3];
        var state = split[4];
        var postalCode = split[5];

       // var address = (streetAddress, city, state, postalCode);
       List<Address> address = new List<Address>();
        

        people.Add(new Person(firstName, lastName, address));

    }

}
