If you filed a Form 4868 extension request using the TurboTax online editions, see this TurboTax support FAQ for how to print the Form 4868 - https://ttlc.intuit.com/turbotax-support/en-us/help-article/printers-printing/print-4868-extension-form-e-filing-turbotax-easy/L6MJM5wAT_US_en_US

If you are using the TurboTax Business Edition for a Partnership, C Corp or S Corp tax return and filed a Form 7004 extension, it will be included in your tax data file on the computer where the software is installed.  Click on Forms.  When in Forms mode locate and open the 7004 so it can be printed.
