Once I complete sale of Principal Residence Form T2091 in TurboTax Standard, does it get filed electronically (via Netfile) with the rest of my 2018 personal tax return?
Yes, the T2091 gets transmitted as well as all the
other forms that you have used in your return. With TurboTax CD/Download, you
can go into Forms Mode (CTRL+R) and any forms that are open there will be
transmitted. You are also given the chance to print out the full return before
you NETFILE, so you can see what will be transmitted.
The only exception would be the T1135 Foreign
Income Verification Statement, which has to be NETFILEd separately from the
rest of the return.
FYI: You can get back to EasyStep Mode by pressing
CTRL+E on your keyboard.
