I'm needing a copy of my accepted tax extension for my bank. Where can I find this in Turbo Tax and is it form 4868

You have to sign onto the TurboTax online account with the same User ID you used to create the account to e-file the Form 4868 - https://myturbotax.intuit.com/

Start the 2023 online tax return by entering some personal information then 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

If you haven't filed yet, the bank has to take your word for it.

If you show an extension request, how does that change your situation with the bank?
