Looping through a range to find a value - excel

Question

I have a worksheet that has columns 1-8, rows 3 through the last row. I would like to loop through each cell to find out if a value of 1 is present. If it is then that row is copied and inserted for each value of 1, additionally that new row will have a text inserted in cell (13,row) then moved to the next row. This is as far as I got....thanks!
Sub Workcenter()
Application.ScreenUpdating = False
On Error Resume Next
Application.DisplayAlerts = False
On Error GoTo 0
Dim Test As Worksheet
Set TS = Worksheets("Test")
Application.DisplayAlerts = True
For k = 1 To 8
For j = 4 To TS.Cells(Rows.Count, k).End(xlUp).Row
If TS.Cells(j, k).Value = 1 Then TS.Cells.Activate
'TS.Cells.Activate.Row.Select
Rows(ActiveCell.Row).Select
Selection.Copy
Selection.Insert Shift:=xlDown
'ShopOrderNumRow = j
Next j
Next k
End Sub

Will try giving some example knowing that I still don't understand how the inserting is occurring for each cell of a row.
Providing more detail, or example of before/after in your post may help.
As for an example, since you're marking only a single cell in each row, I would suggest Find() for value of 1 to determine if you need to write to that specific cell.
'untested code
sub test()
toggle false
dim rowNum as long
for rowNum = firstRow to lastRow Step 1
with sheets(1)
with .range(.cells(rowNum,1),.cells(rowNum,8))
dim foundCell as range
set foundCell = .find(1)
if not foundCell is nothing then .cells(rowNum,13).value = "text"
end with
end with
next iterator
toggle true
end sub
private sub toggle(val as boolean)
with application
.screenupdating = val
.enableevents = val
end with
end sub
Edit1: Looks like countif() may be the saviour here.
Edit2: Tested code input (untested code part of Edit1)
Sub test()
Dim lastRow As Long: lastRow = 10
Dim firstRow As Long: firstRow = 1
toggle False
Dim rowNum As Long
For rowNum = lastRow To firstRow Step -1
With Sheets(1)
Dim countRange As Range
Set countRange = .Range(.Cells(rowNum, 1), .Cells(rowNum, 8))
Dim countOfOnes As Long
countOfOnes = Application.CountIf(countRange, 1)
If countOfOnes > 0 Then
With .Rows(rowNum)
.Copy
.Offset(1).Resize(countOfOnes).Insert Shift:=xlDown
End With
.Cells(rowNum, 13).Value = "text"
End If
End With
Next rowNum
toggle True
End Sub
Private Sub toggle(val As Boolean)
With Application
.ScreenUpdating = val
.EnableEvents = val
End With
End Sub
