What can TurboTax users do if they have additional income sources not covered in initial data entry?

TurboTax is designed to allow users flexibility in managing their tax information throughout the preparation process. When additional income sources arise that were not included in the initial data entry, users can conveniently add them later in the tax preparation process. This ensures that all income is accurately reported, which is important for the integrity of the tax return and potentially affects the user's overall tax liability.

Accurate reporting of all income sources helps avoid issues with the IRS, as it’s important to declare all forms of income to comply with tax laws. This choice reinforces the comprehensive nature of TurboTax, which accommodates changing financial circumstances and encourages thoroughness in tax reporting.

In contrast, disregarding the additional income, filing without reporting it, or only reporting if it's above a certain threshold can lead to misreporting that could result in penalties or audits, thus highlighting why adding them later is the most appropriate and responsible course of action in the tax preparation process.
