3) Complete one section at a time.
Preparing taxes can take time, and it's important to get it right the first time. To ensure your return is complete, focus on one section at a time. If you feel tired working on a particular part, take a break and return when you're refreshed. It's common for people to leave an income item unfinished and never come back to complete it, which can lead to errors and problems.
If you find missing items like receipts or an IRS form, use the bookmark feature at the top of each screen to mark those sections. This will remind you to revisit them later, and the bookmark function allows you to navigate directly to where you need to go.
If there's a missing item and you're tempted to enter a temporary estimate to see your refund or tax due, remove the estimate in the same session and bookmark the page. You don't want to accidentally file your return with incorrect information.
