Populating a lookup field from another lookup field

hello everyone,

i am trying to create a phone call task after creating an opportunity but the problem i need to populate a lookup field called "to" from the account lookup field that located in opportunity "parentaccountid" here is my code:

     {
                // TODO: Implement your custom Plug-in business logic.

               // QueryExpression query = new QueryExpression("opportunity");
              //  query.ColumnSet.AddColumn("parentaccountid");
                var accountLookup = (EntityReference)entity.Attributes["parentaccountid"];
                var accountName = localContext.OrganizationService.Retrieve(accountLookup.LogicalName, accountLookup.Id, new ColumnSet(true));

                Entity opportunityCall = new Entity("phonecall");
                opportunityCall["description"] = "opprotunity forwaded call";
                opportunityCall["scheduledend"] = DateTime.Now.AddDays(7);//"10/28/2017";
                opportunityCall["directioncode"] = true;
                opportunityCall["to"] = new EntityReference("account", accountName.Id);
                if (localContext.PluginExecutionContext.OutputParameters.Contains("id"))
                {
                    Guid regardingobjectid = new Guid(localContext.PluginExecutionContext.OutputParameters["id"].ToString());
                    string regardingobjectidType = "opportunity";
                    opportunityCall["regardingobjectid"] = new EntityReference(regardingobjectidType, regardingobjectid);
                }
                localContext.OrganizationService.Create(opportunityCall);

            }
