How do I open an additional form?

What forms are you looking for?  If you are looking for a particular form on the download version you can click on the bottom where it says forms and search for the form by entering the name of it in the search area.

I use TurboTax downloaded to my computer. I need to fill two forms T746, one for each year (as per item 1 on the form).  I filled one form, but do not know how to open the second form.  Please advise.
