Так "Моя сім'я хоче їхати кудись", як каже аудіо, чи "Я іду кудись, не знаю куди"? Коли почнеться робота над помилками?
Please do not duplicate your reports in the comments. It's not gonna change anything, only create clutter. This comment is not relevant anymore, but occupies the top place.
That is kind of very poetic, epic and obsolete... At least I think so...
If you are trying to say that your answer was correct apart from using "don't" instead of "do not" (or the other way around), then no, Duolingo is not sensitive to this, it accepts either form automatically.
If your answer was not accepted, it means something else was wrong. Please always include your full input. I cannot tell you now what was wrong because you were overconfident, decided on your own that it was to do with "don't/do not" and didn't show me your complete input sentence. If you did, I would have been able to give my comment and help you.
