If these instructions do not work for you then you can try this
option to print your return:
To get whole return with all the worksheets please log back in your
TurboTax account and "add a state" to open the return back up (you
are not really adding a state, just to open it back up), then select Tools,
Print Center and choose the print center, then select returns and choose the
radio button to include all worksheets.
