@user17731989344 TurboTax Desktop for Tax Year 2025 allows one account per license code. As of the last tax season, you must log into your TurboTax account or create one to use your software.
This change benefits our customers by saving their license code to their TurboTax account. You can download the software on up to three computers using the TurboTax account associated with your license code. This simplifies the process, as when you are logged into your account on a new computer, the license code will already be available for you to click on. You can still complete 8 to 12 returns (depending on the product you purchased) and use NetFile as before.
In terms of installing TurboTax Desktop on 3 Windows OS, it has not changed, and it's still the same.
