Thank you! This clarifies the whole thing.
I wish the Intuit customer service rep. knew this, and explained it when I called them, instead of telling me the non-sense that the profit sharing does not count towards the total, maximum allowed 401(k) contribution.
They should also fix the software to catch cases where one is exceeding the limit (I tried exceeding the limit and succeeded - TurboTax did not catch it, even after it validated and verified everything, several times). The very least they can do is if one checks the Maximize My Return box, the software can automatically clear the three boxes above it - as simple as that.
