Simple enough:
private void M2_SaidaEfetiva_Click(object sender, EventArgs e)
{
    var theForm = Application.OpenForms.OfType<Frm_Saida>().FirstOrDefault();
    if (theForm is null)
    {
        theForm = new Frm_Saida();
        theForm.MdiParent = this;
        theForm.Text = "Saídas Efetivas";
        theForm.Tag = "1";
        theForm.Show();
    }
    
    theForm.Activate();
}
