@JWL2672a if you had to get a new machine or had to reformat the old one and re-install s/w, you may not be able to reactivate old versions of Turbo for 2019-2020 and shortly 2021 will drop off when 2025 is released - Intuit supports activation of current tax year and 3 prior years. Turbo prior to 2019 didn't use this new license activation server so can probably be re-installed.
