I am trying to view and print my returns before I transmit them, however, when I press the "View or print returns" box, it shakes, and then nothing. What do I do now?

I see your question is 2 days old, so it must have become orphaned in the flow.   You may have already been able to view the returns.   In any case, I stumbled onto your question, so here's a way to view/print at the Print Center.

With your return open, click in the left menu column on TAX TOOLS, then choose PRINT CENTER.

Then choose "Print, save, preview this year's return."   If you haven't already paid, it will ask you to do so first.
