Why re: turbotax: why am I only able to print ta state return, yet can not print a federal return? Any ideas?

The complete federal and state tax returns for 2019 along with all worksheets and information only pages will not be available in the PDF download until the online editions for tax year 2020 become available in early December.

This occurs each tax year after the prior year online editions shut down at the end of October.  It is always a good idea to download a PDF of your tax return after it has been accepted by the IRS along with the tax data file (.tax)

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.
