I am working in a Custom Opportunity Clone and am trying to clone the Sales Team when I recieve the following error when I click the clone button:

System.DmlException: Insert failed. First exception on row 0 with id 00q50000002eoQZAAY; first error: INVALID_FIELD_FOR_INSERT_UPDATE, cannot specify Id in an insert call: [Id]



Class.OpportunityCloneWithItemsController.MyClone: line 94, column 14 External entry point 

Here is the code in question to clone the sales team:

             // copy over the Opportunity Sales Team - ONLY INCLUDE THE FIELDS YOU WANT TO CLONE
             List<OpportunityTeamMember> team= new List<OpportunityTeamMember>();
             for (OpportunityTeamMember otm : [Select id, TeamMemberRole,OpportunityAccessLevel, 
                  Userid, opportunity.id From OpportunityTeamMember where Opportunity.id = :o.id]) {
                  OpportunityTeamMember newotm = otm.clone(true);
                  newotm.opportunity = otm.Opportunity;
                  team.add(newOtm);
             }
             insert team;
      

Here is the entire code:

public with sharing class OpportunityCloneWithItemsController {

    //added an instance varaible for the standard controller
    private ApexPages.StandardController controller {get; set;}
     // add the instance for the variables being passed by id on the url
    public Opportunity o {get;set;}
    // set the id of the record that is created -- ONLY USED BY THE TEST CLASS
    public ID newRecordId {get;set;}


    public OpportunityCloneWithItemsController(ApexPages.StandardController controller) {

        //this.controller = controller;

        // load the current record
        o = (opportunity) controller.getRecord();
        system.debug('********** ' + o);
    }
    
    // method called from the VF's action attribute to clone the Opportunity
    public PageReference MyClone() {
 
         // setup the save point for rollback
         Savepoint sp = Database.setSavepoint();
         Opportunity o;
         Opportunity newO;
 

              //copy the Opportunity - ONLY INCLUDE THE FIELDS YOU WANT TO CLONE
             o = [select

             newO = o.clone(false);

    newO.Name = 'Cloned - ' + o.Name;
    newO.StageName = 'Prospecting';
    newO.CloseDate = o.CloseDate + 700;
    
             insert newO;
         System.debug('******* ID: ' + newO.ID);
    
    //Reset the Opp ID and resset fields to default values

    

             // copy over the Opportunity Sales Team - ONLY INCLUDE THE FIELDS YOU WANT TO CLONE
             List<OpportunityTeamMember> team= new List<OpportunityTeamMember>();
             for (OpportunityTeamMember otm : [Select id, TeamMemberRole,OpportunityAccessLevel, 
                  Userid, opportunity.id From OpportunityTeamMember where Opportunity.id = :o.id]) {
                  OpportunityTeamMember newotm = otm.clone(true);
                  newotm.opportunity = otm.Opportunity;
                  team.add(newOtm);
             }
             insert team;
      


     return new PageReference('/'+newO.id+'/e?retURL=%2F'+newO.id);
   return new PageReference('/'+  newO.Id);

    }

}

How do I solve this error?

Thank you
