Sorry Turbo Tax doesn't have a copy of your W2, only the entries you made for it. Turbo Tax only has a Wage and Tax Statement worksheet. But you can't use it to prove anything. It might have imported or been entered wrong. The worksheet would be included in the PDF of the tax return if you downloaded the PDF to include All forms and worksheets in the tax year the return was completed. The return combines all your wages on line 1a.
You need to ask your employer for another copy. Or you can get your W2 information from the IRS, see this….
