@mjrengaw I wrote the date of my comment to indicate the situation as of that date, not to indicate whether or not anything had changed from previous behavior.
There are two issues here. First, whether or not the values should be rounded before summing them. Second, whether there are errors in rounding the values.
There are various debates about the first issue, but there should be no debate about whether or not there should be errors in rounding the values - there should not be rounding errors, and Intuit needs to fix those rounding errors whether or not they change where in the calculation they round the numbers.
The fact that this behavior has persisted for a long time just indicates how unresponsive Intuit has been to this problem.
