It won't always match because there are over a dozen items that might not be on your W-2, including unreported disability or sick pay, scholarship or fellowship income, taxable tips, and dependent care or adoption benefits, just to name a few.

If you're using the CD/download TurboTax software, you can see exactly what's included in Line 1 by switching to Forms mode, opening your Form 1040, right-clicking the amount on Line 1 and choosing Data Source, and then selecting the Wages, Salaries & Tips Worksheet.
