Turbotax made errors in calculating Age Exemptions

[Trevor09]

NOA shows that the Age Exemption amounts for Federal and Provincial taxes submitted by Turbotax were significantly wrong. This switched result from a refund to a payment due.   Looks like Turbotax used the T1 Worksheet to make the calculations.   Is this a known error?  I have used Turbotax for about 10 years without such errors.  Can I claim something under the Turbotax guarantee of 100% accuracy?
