TurboTax will not have that information. As a working adult, you are supposed to keep track of your own employment history. You can get a wage and income transcript from the IRS that will show the W-2's or 1099's that you received income from, but that will not show the actual dates you were employed--only the tax years for which the income was reported. You could also check with Social Security to see the employment that was reported to SS.
