The taxpayer (you) is responsible for keeping all records, including past tax returns.
If you use the CD/download TurboTax software, you may be able to open your 2022 tax return to look for numbers there, but users of the CD/download software are responsible for preserving their own files.
If you use the Online TurboTax product, the current Online product is only for the current tax year (now 2024).
So when you file a return, it is a very good idea to download a PDF copy of your tax return and all schedules with it.
What is it that you are being asked to provide?
