underpayment of tax

I got part way through the underpayment of tax section on TT Premier and need to recheck/possibly change some answers.  When I click the back button it won't let me go back to those questions, just takes me back to the Other Tax Situations main page.  Have tried multiple times.  How can I go back and make changes to the questions I previously answered?  And, as long as I have not filed yet, can I go back additional times?  I am still not sure about some of the answers since I never had an underpayment penalty before.
