You don't need the tax files for all the previous years. When you start your 2023 tax return, information is transferred only from the 2022 file. Information is carried from year to year, so the 2022 file includes any losses that were carried over from earlier years. The only file you need is the .tax2022 file. You do not need the 2022 program or CD, just the .tax2022 tax return file.
Since you are using a new computer, TurboTax for 2023 will not automatically find the 2022 file. On the screen that looks for the previous year's tax return you will have to click the Browse button, find the .tax2022 file, then click Open.
