Unfortunately, you are correct. If there was a miscalculation for the stimulus payments, the tax return was automatically corrected by the IRS. However, due to the unprecedented demands on their limited resources, the refunds have been delayed for many filers.
Please clarify what happened. TurboTax is software for self-prepared returns and relies on users to enter their details accurately.
The Recovery Rebate Credit was used to report eligible stimulus payment amounts not received. The 100% accuracy guarantee is for all software calculations, but would not include users accidentally including wrong amounts.
It is up to taxpayers to check their results, including imports, before submitting their tax returns.
