If you are using the TurboTax desktop CD/Download editions click on Forms at the top of the desktop program screen.
When in Forms mode on the left side of the screen click on Tax Payments to open the Tax Payments worksheet. All of your payments will be listed. See if there is a discrepancy of amounts on the worksheet. If there is an amount in one of the boxes that is prefilled and not editable, then click on on the box and there should be a magnifying glass icon. Click on the icon which will take you to where that amount was entered.
