See if it will still let you do this, but you need to do it quickly, since after October 20, you may not be able to get back in this way.
If your PDF you downloaded at the Tax Home doesn't have the worksheets in it, here's how to open your return back up to go the Print Center where you can choose various PDFs that include the worksheets. There should be Wage and Tax worksheets, for instance, for each of you, which should show your wage income for each. And also, the Wages, Salaries, and Tips worksheet has columns showing those types of income and some other information for Taxpayer and Spouse on one worksheet. Other types of income may not be so easily split out. You'll just have to look at the worksheets for those topics to see if they have the info you need.
NOTE: When you open your return back up, do not make any changes in it since it's already been filed.
NOTE: Do NOT use this method to open a return to make changes/edits to an already-filed return (one that has actually been mailed or efiled.) If you later need to make changes to an already-filed return, you have to go through the formal amending process, and your return must start off exactly as 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.
