These two errors were reported months ago and again a week ago. It appears that the determination of the deductible amount is done as a separate calculation using the correct limits, so this problem shouldn't be affecting your ability to file. It appears that the calculations that actually involve lines 9 and 17 in TurboTax are used only to display in step-by-step mode the maximum permissible elective deferral without regard to any limitation based on net earnings, so these two errors can be ignored as long as you do your own determination of the regular elective deferral and catch-up elective deferral. Even the Maximize function works correctly despite these two errors. Ignore everything you are told in step-by-step mode about how much you are eligible to contribute as employee and employer.
