I just got this same CP2000 telling me I have two weeks to send them $3,000. The data was imported from Compushare. It appears they have the reported data and the data that "I furnished" through Turbo Tax but cannot view on the return or anywhere else to test its accuracy. The IRS is reporting my taxable income from column 1d Proceeds, while the reported values are coming from column 1e Cost basis! The numbers line up if these columns are swapped. Thus two $4,000 options are reported as $0 income. These two items are different than the others in that they are in Box 5 "non covered security" while the others are "Short Term". These Short-Term options are slightly off and the IRS reports this discrepancy. The result is an 8K underpayment and at big bill plus $170 interest. It looks like Turbo Tax made the mistake and there is no way to actually see the numbers to verify them.
It seems that if you have anything but plain vanilla wage and dividend income, it's much safer to get an accountant than do it on your own withTurbo Tax. I've been using Turbo Tax for over 10 years and this really sucks.
