Hi, HemlockPrinters.

Edit: Minor change - ScreenUpdating turned off.

Please see attached. The code is... 
Option Explicit

Sub Format_Totals()
Dim xCell As Range

Application.ScreenUpdating = False
    
    For Each xCell In Range("A1:A" & Range("A1").SpecialCells(xlLastCell).Row)
        If xCell = "Subtotal:" Then
            xCell.Offset(0, 1).Font.Underline = xlUnderlineStyleSingle
            With xCell.Resize(1, 2).Font
                .FontStyle = "Bold"
                .Size = 11
            End With
            xCell.Offset(1, 0).EntireRow.Insert
        ElseIf xCell = "Total:" Then
            With xCell.Resize(1, 2).Font
                .FontStyle = "Bold"
                .Size = 12
            End With
            xCell.Offset(0, 1).Font.Underline = xlUnderlineStyleDouble
        End If
    Next

Application.ScreenUpdating = True

End Sub
