Can't print forms that need to be mailed in

After completing the e-file I received a message that some forms need be mailed in complete filing my taxes.  I click on the print button and a pop-up window opens but says Turbo tax is having printing problems, try again later.  I kept trying for an hour and gave up and clicked on Continue at the bottom.  Now I have no idea what forms I needed to print to mail out.  Please help!  I have no messages from Turbo tax to indicate what forms needs to mailed in the next 3 days.  Where can I find this info?
