Received IRS Notice CP11 concerning Form 6251 miscalculation

I received IRS Notice CP11 which stated that the IRS changed my tax return and I owe almost $2,000.00. They state that there was either an error in the computation for the AMT on Form 6251 or an error in the Transfer of the Form 6251 amount to my return. All these calculations are done by TurboTax, so I don't understand why there is computational error or an error in transferring the amounts.

 

The notice provides side-by-side values of how Turbo Tax calculates Adjusted Gross income (Form 1040 line 11) and how the IRS calculated it. They are identical. Same with Taxable Income (Form 1040 line 15). Identical again. However, the calculated value for Total Tax (Form 1040 line 24) is different.

 

The CP11 also lists "Your payments and credits". All these, including the total, match exactly what I have in my return.

 

I need to understand why the Turbo Tax's calculated "Total Tax" is not the same as what the IRS calculated.

 

I've been using TurboTax since 1999, and this is the first time I've been challenged by the IRS.
