Starting an online tax return in TurboTax is straightforward. Here are the steps:
Gather Your Tax Information: Before you begin, make sure you have all your necessary tax documents, such as W-2s, 1099s, and receipts for deductions.
Create an Account: If you haven’t already, sign up for TurboTax online. You can use last year’s info to jumpstart your return.
Enter Your Information: Follow the prompts to input your personal and filing details. You’ll need to provide information about your income, deductions, and any other relevant tax items.
Review and File: TurboTax will guide you through the process, checking for errors and ensuring accuracy. Once you’re ready, review your return and submit it electronically (e-file).
if you installed a desktop version, there should be an icon on the desktop that you double-click on to start.
