I think you mean the W2? The W4 you fill out to give your employer to tell him how much withholding to take out. Turbo Tax doesn't have or keep copies of your W2. Only the info that was entered from them. You need to keep your own copy or ask the employer for another one. If you need to see a W2 you entered, you have to download your whole return with all the worksheets.

If you used the Desktop CD/Download program then the only copy is on your computer and not saved or stored online. So you need to make and keep your own backups.
