TurboTax does not have a copy of the W-2 or Form 1099. It would have W-2 and Form 1099 worksheets that included the tax data from the forms that were entered. The worksheets would be included in the PDF of the tax return in the tax year the return was completed.
Copies of a Form 1099 would have to obtained from the issuer of the form.
The 2018 worksheets will be included in the 2018 PDF of your tax return after the 2019 online editions become available in December of 2019.
