OK, nevermind, figured it out:

Private Sub btn_StartNewSeason_Click()

Dim wbNew As Workbook
Dim wsNew As Worksheet
Dim Rng As Range
Dim i As Long
Dim J As Long

    Set wbNew = Workbooks.Add("C:\....\templateseason.xlsm")
  Set Rng = Worksheets("Client List").Range("A1")
    For i = 0 To lstBrandsNewSeason.ListCount - 1
        For J = 0 To lstBrandsNewSeason.ColumnCount - 1
            Rng.Offset(i, J).Value = lstBrandsNewSeason.List(i, J)
        Next J
    Next i
    
    wbNew.SaveAs Filename:="C:\...\" & txtNewSeasonName.Value
    wbNew.Close
    Unload Me
End Sub
This was the proper code needed...Thanks to both of you!!
