Clear Checkboxes macro

I have the following macro and need to insert a command where ******* is to clear the checkboxes that are on sheet "ExpenseEnter". I don't know how to write this part of the code.

Sheets("Launch").Select
    Sheets("TimeEnter").Visible = True
    Application.Goto Reference:="ClearTime"
    Selection.ClearContents
    Sheets("TimeEnter").Select
    Sheets("MilesEnter").Visible = True
    Application.Goto Reference:="ClearMiles"
    Selection.ClearContents
    Sheets("ExpenseEnter").Visble= True
    Application.Goto Reference:="ClearExpense"
    Selection.ClearContents
    Sheets("ExpenseEnter").Select
   
 *******

    Sheets("MilesEnter").Select
    ActiveWindow.SelectedSheets.Visible = False
    Sheets("TimeEnter").Select
    ActiveWindow.SelectedSheets.Visible = False
    Sheet("ExpenseEnter").Select
    ActiveWindow.SelectedSheets.Visible = False
    End Sub
