How do I access schedule D and supporting schedules

If you are using online TurboTax you do not have direct access to the forms and schedules.  If you are using desktop software, go to the top of your TT tool bar and click the word "Forms" for Forms mode.  When you are ready to leave Forms mode, go to that same spot and click Easy Step.

If you are using the desktop version, you will just click on Forms mode at the top of the screen.

If you are using the online version, you can not make any types of changes or entries on the forms, but you can access the Schedule D using the Print Center
