when IDENTITY_INSERT is set to OFF - SQL SERVER

Now that I execute the trigger, it does not allow me to insert. I get the following:

  

Msg 544, Level 16, State 1, Procedure TR_TB_DISTRITO_INS, Line 5 [Batch Start Line 28] Can not insert explicit value for identity column in table 'TB_DISTRITO_AUDITORIA' when IDENTITY_INSERT is set to OFF.

This is my TB_AUDITORIA for the district table:

Create table [TB_DISTRITO_AUDITORIA] 
(
    [COD_DIS] Integer Identity(101,1) NOT NULL, 
    [NOM_DIS] Varchar(30) NOT NULL,
    [FECHA_ACCION] DateTime,
    [ACCION] varchar(20)
) 
alter table [TB_DISTRITO_AUDITORIA]
alter column [COD_DIS] INTEGER NOT null
go

This is my audit trigger for insert:

create trigger [TR_TB_DISTRITO_INS]
on [TB_DISTRITO]
for insert
as
insert into [TB_DISTRITO_AUDITORIA]
(COD_DIS,NOM_DIS,FECHA_ACCION,ACCION)
select COD_DIS,NOM_DIS,GETDATE(),'INSERTADO'
from inserted
go

And this is my TB_DISTRITO

Create table [TB_DISTRITO] (
    [COD_DIS] Integer Identity(101,1) NOT NULL,
    [NOM_DIS] Varchar(30) NOT NULL,
Primary Key  ([COD_DIS])
) 
go

I appreciate the help in advance.
