TurboTax Rounds Estimated Taxes and Causes Refund to be Incorrect

When I enter the estimated taxes paid, TurboTax rounds them to the nearest dollar.  When I received the refund, the IRS did not round the estimated taxes, as a result the refund was not the same as the amount shown in TurboTax. TurboTax should not be rounding Estimated Taxes since the IRS expects the exact amount to be reported.
