I think you missed it completely. I calculated and paid the tax liability owed. The IRS returned money to me that I NEVER gave them. I make four quarterly payments for my estimated tax bill. Both the IRS and Turbotax calculated the same tax amount due. However, the IRS said I paid more money than I did. This only happened because I put the estimated payments amount on the wrong line in Turbotax. I find it hard to believe the IRS does not verify monies received for tax payments before sending out refund checks that are clearly in error.
