There's no link to my tax return.  I need to be able to read the numbered lines of my tax return.

As far as I know, TurboTax Online does not provide direct access to forms, nor can you save the working file itself on your computer. When you sign up for the cloud, you're stuck in the cloud, it seems.

That said, you should be able to print your actual returns to PDF, which you can save on your computer and open with a PDF reader to view the returns. As far as I can tell, this should apply to all versions of TurboTax:
