It seems impossible to get a copy of my 2023 extension that was filed through turbo tax. Does anyone know how or who to contact?

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/

Start the 2023 online tax return by entering some personal information then click on Print Center.  Then click on Print, save or preview this year's return.  Choose the option Include government and TurboTax worksheets

You will be asked to pay for the online account (if not using the Free online edition) before you can access the forms, schedules and worksheets in the account.
