If I upload all my docs used for completing my TurboTax (1099's, etc.) return can I then throw out the paper copies? Will that work for the IRS if I'm audited?

For example, I keep 7 years of Turbo Tax returns in a physical file. I use the online version of Turbo Tax.  If I upload my paperwork to "my documents" in Turbo tax with my return, can I then throw out the original papers?
