The TaxAct program will only print both pages 1 and 2 of Form 8949 if you have entered both short- and long-term transactions, per the IRS Instructions for Form 8949, page 3:
You don't need to complete and file an entire copy of Form 8949 (Part I and Part II) if you can check a single box to describe all your transactions. In that case, complete and file either Part I or Part II and check the box that describes the transactions. Otherwise, complete a separate Part I or Part II for each category of your transactions, as described above.
