The IRS does have an electronic record of your W-2, if one was issued. Check your Wage and Income transcript here.

Also, be aware that not all employers make their W-2s available for direct download into Turbotax, only some do. Your W-2 should be mailed to you by January 31 after the close of the year, unless you consented to electronic delivery, and you can type in your details from the printed or electronic copy even if you can't download it. You are ultimately responsible for obtaining and keeping your important tax documents.
