I do I print my 2018 taxes without all 108 pages? Which are the pages that need to be printed?

[DoninGA]

For the federal tax return?  The Form 1040 and all supporting forms and schedules that have an Attachment Sequence Number in the upper right corner of the form or schedule.

Using the PDF reader you can choose which pages to print ... do not just print everything.  

The actual return starts with the 1040 and continues thru the schedules and forms ... they have a sequence number on them.  The fed & TT worksheets are for your reference only ... they are not part of the actual return that was filed. 

In the future ... after you file and before the program closes the end of October ... you need to log back in and scroll down and click on ADD A STATE to open the closed file ... then click on the Print Center and choose to save the return with and without the worksheets  for your records ...
