I purchased 2 copies of turbo tax deluxe for desktop. Can I load both to the same computer?

No.  You cannot install 2 personal TurboTax desktop products on the same computer.  Why would you consider loading 2 copies of Deluxe to the same computer?   What are you trying to accomplish?   We can tell you more once we understand your goal and concerns.

not only can you not load 2 copies of Turbotax for 1040s but you also can't e-file more than 5 returns. This is an IRS restriction, Not TurboTax.

I am doing taxes for 9 people in my family. I knew that I could only e-file 5 returns so that is why I purchased a second license so that I could do the remaining 4 members of my family. I am not a tax professional.
