If your 2018 PDF doesn't yet have the worksheets, you'll likely have to wait a couple of weeks. Every November, the PDF files are in a state of transition as they are moved and archived. So there is no trick to get the larger PDF with the worksheets during this limbo period. You'll need to come back and try again periodically. At some point the 2018 PDF should have the worksheets, but it may not be before December.
