Some versions of turbotax allow you to take a picture and the program will grab the numbers off the form and input them for you, instead of typing them in.
Other than that, there is generally no need to include a copy of your W-2 with your e-filed tax return. In rare cases, the IRS may contact you later and ask you to send a copy (such as, if your employer never sends in the employer copies) but most of the time it is not needed.
