You can accomplish this requirement using process builder.

Hi Jordan,
Description is already standard field on Account object and as well as on Contact object. You don't need to create this field on both objects. 
trigger UpdateContactField on Account (after insert, after update)
{
    List<Contact> con = new List<Contact>();
     
    for(Account a : Trigger.new)
    {
        if(a.Description != null)
        {
            Contact ct = new Contact();
            ct.lastname = a.name;
            ct.AccountId = a.Id;
            ct.Description = a.Description;
            
            con.add(ct);
        }      
    }
    
     insert con;
}
Mark this best answer if this helps.
