How many times can I use TurboTax online?

I'm curious about the usage limitations of TurboTax online. Could you please elaborate on how many times I can utilize this software to file my taxes? Is there a set limit per year, or can I use it multiple times as needed? Additionally, are there any restrictions based on the number of returns I need to file, or if I'm using it for personal or business purposes? Understanding these details is crucial for me to make an informed decision about whether TurboTax is the right tool for my tax filing needs.
