When I downloaded my 2019 return, it is only 6 pages long. My previous years were over 100 pages. Am I missing something?

the 2019 file contains only the forms required for filing while the previous year contained worksheets and other supporting schedules that didn't need to be filed.  except for the 1040 itself, required forms and schedules have an attachment sequence number in the upper right.  those that are not required do have this info

Well here is the scoop ...  Right now the 2019 returns are being archived so  since you did not save a PDF with the worksheets BEFORE the online system closed this year you will need to wait until early December when the Online system opens back up for the 2020 tax year. 

At that time you will be able to download a new PDF which will include all the worksheets ... all you have right now is the return as filed and not all the extra worksheets that are not sent to the IRS.
