TorboTax doesn't "search" for anything outside of the TurboTax program per-se. If the accounting service used by your particular employer participates in the online system for W-2's that TurboTax participates with, then you'll be able to download/import your W-2 when said W-2 is released by the payroll service for download/import.
This year we've made importing your info into TurboTax easier than ever before! You can successfully import your info directly from your employer. If TurboTax doesn't recognize your employer's EIN for any reason, you'll have the option to snap a photo of your W-2 using your smart phone.
Requirements to successfully import your W-2 directly from your employer
If you're unable to import directly from your employer, you'll have a chance to snap a picture of your W-2 using your smart phone camera.
Let's import your W-2!
If you don't have your employer's EIN or would prefer to skip the import options, you can open a screen to manually enter the info from your W-2 instead.
