The Form 4868 should be in the file if you use Print Center and the option for all worksheets, assuming that you used the TurboTax Easy Extension website to e-file the extension request with the same User ID for the 2020 account to complete the federal and state tax returns.
To access your current or prior year online tax returns sign onto the TurboTax website with the User ID you used to create the account - https://myturbotax.intuit.com/
When you sign onto your online account and land on the Tax Home web page, scroll down and click on Add a state.
This will take you back to the 2020 online tax return.
Click on Tax Tools on the left side of the online program screen. Then click on Print Center. Then click on Print, save or preview this year's return. Choose the option Include government and TurboTax worksheets
