Have you already filed and are printing for your records?
If you just recently efiled, has your return been accepted? If not yet accepted, it's best to wait until it is, then your return PDF should also have the electronic postmark in it for your records. But the following may explain your current issue:
After one has efiled and been accepted, it can sometimes take a return PDF a while to update and become available at the Tax Home. And it may not have the worksheets. Here's an alternate way to print by opening the filed return back up to print at the Print Center.
NOTE: When you open your return back up, do not make any changes in it if it has already been filed. If you later have to amend the return, it has to start off exactly as it was when it was originally filed.
NOTE: Remember all PDF tax documents and tax data files are very sensitive files, since they contain your personal ID info, financial data, and possibly bank account numbers, etc. Be sure to store them safely and securely to guard against computer theft, hacking, etc.
