The form "Tax Withholding by Quarter" works incorrectly. It shows:
Enter your total withholding for all four quarters. Do not include any estimates. Enter zeros for periods for which there was no withholding.
Note: The total withholding you enter below must equal $XXX.
The problem is that $XXX does't match withheld taxes in imported W-2 forms.
I do not trust TurboTax to file my taxes when they can't even sum up two numbers.
