Saving Your Tax Return as a PDF (Portable Document Format File)
Although TurboTax saves your tax return as a tax data file (.tax file), it's not a bad idea to also save your return in PDF format, which can be viewed or printed using the free Adobe Reader or Foxit Reader software.
This lets you view and print your tax return should your tax file gets corrupted or if you no longer have the TurboTax software. The government also accepts a paper-filed return printed from the PDF.
Please note that TurboTax PDF files cannot be "read" by the TurboTax software the way the tax data file can, which means they cannot be used for amending, troubleshooting calculation issues, or for full prior-year transfer capabilities.
