Get your taxes done using TurboTax

@robtm I know how to use split-screen mode (good thought), but I am unable to open a second instance of TT.  When I try to open TT again, I end up back at the instance I already have open.

Maybe my question should have been a little clearer:

I want to open two returns that I am currently working on at the same time so that I can compare and/or change values in either one without switching back and forth between those returns using File -> Open Tax Return.

I don't want to save each return as a PDF to compare then have to keep switching in TT to make changes then save it as a PDF again.
