Please try this...

Sub CopyDataToMasterSheet()
Dim wsSummary       As Worksheet
Dim ws              As Worksheet
Dim dlr             As Long
Dim RngTotal        As Range
Dim r               As Long

Application.ScreenUpdating = False

Set wsSummary = Worksheets("Summary")

For Each ws In ThisWorkbook.Worksheets
    If Not ws Is wsSummary Then
        Set RngTotal = ws.Columns(1).Find(what:="Total", lookat:=xlPart)
        If Not RngTotal Is Nothing Then
            r = RngTotal.End(xlUp).Row
            If wsSummary.Range("H1").Value = "" Then
                dlr = 1
            Else
                dlr = wsSummary.Cells(Rows.Count, "H").End(xlUp).Row + 1
            End If
            ws.Range("A" & r).Copy wsSummary.Range("H" & dlr)
            ws.Range("J" & r).Copy wsSummary.Range("I" & dlr)
            ws.Range("Q" & RngTotal.Row).Copy wsSummary.Range("J" & dlr)
        End If
    End If
Next ws
Application.ScreenUpdating = True
End Sub
