If you are not getting a complete return then you will need to wait until sometime in December when they have finished archiving the 2019 returns and the Online system comes back online.
If you need a copy before then ...
Go to this IRS website for free federal tax return transcripts - https://www.irs.gov/individuals/get-transcript
For a fee of $50 you can get a complete federal tax return from the IRS by completing Form 4506 - http://www.irs.gov/pub/irs-pdf/f4506.pdf
Going forward ... ALWAYS save a PDF with and without the worksheets BEFORE the online system closes mid October.
