It gave me no error message when it completed the calculations on the parent's Form 8615 worksheet which is part of the child's tax return.  It had a completely different tax figure on line 9 when I completed this in May from when I went to e-file the tax return over the weekend.  

There was obviously an error in their calculations for Form 8615 parent's worksheet that got fixed on a recent update, but they did not provide any notifications about this.  Don't you think they should have sent out an alert about this?  How many tax returns were affected by this?
