What is the primary purpose of Intuit TurboTax?

The primary purpose of Intuit TurboTax is to help users prepare and file their federal and state income tax returns. This software provides a user-friendly platform where individuals can input their financial information and receive guidance through the tax filing process. It automates many aspects of tax preparation, which allows users to carefully review their financial situation and ensure compliance with tax laws.

TurboTax is specifically designed with features that cater to both simple and complex tax situations, making it accessible to a wide range of users. By streamlining the filing process and automatically calculating deductions and credits applicable to the user's tax situation, it simplifies what can be a daunting task for many.

The other choices focus on related areas but do not capture the main objective of the software. While providing financial advice might be a benefit of using the tool, it is not the primary function. Similarly, calculating investments pertains to specific financial planning aspects rather than directly to tax preparation.
