Put a checkBox as "checked" using an HTMLHelper

my question is short, in which part I must add the property of checked in my HTMLHelper , since I must show it by default as selected, I looked in the microsoft documentation but found nothing about it :(

so I tried to do it, but it did not work

 @Html.CheckBoxFor(model => model.Estatus, new { htmlAttributes = new { @checked = "checked" } })
