If you used the desktop CD/Download editions installed on your computer, the only copy of your tax data file and any PDF's will be on the computer where the return was created. TurboTax does not store online any returns completed using the desktop editions.
If you used the TurboTax desktop editions to complete and file the 2023 tax return, then you need to start the TurboTax program for tax year 2023 on your computer. Once the 2023 program is started Continue the tax return you want to amend. When the tax return is opened -
Click on Federal Taxes (Personal using Home & Business)
Click on Other Tax Situations
Under Other Tax Forms
On Amend a return, click on the start button
