Be sure to create and save PDF files of each of those prior years before you do anything...and back-them-up on a USB Flash drive.

You can probably only re-install the software for years for 2022, 2023, and 2024 (2021...maybe, but probably not). Activation codes should be in your intuit account, they show up in mine.....unless (perhaps) you bought them from a 3rd party, and not directly from TTX.
TTX will only let you re-install those last three years, and nothing earlier....so get those earlier PDF files created and saved...even maybe printing out the basic filing-only copies.
