I have $10,000 saved. Where should I invest it for high return quickly. (not stock market)?

No one can give a good answer with a specific investment without knowing more about your situation. What I can give you is some general guidelines to consider.

The higher the potential monetary returns the higher the risk of losing money. Unless you understand the investment well enough to manage the risk you probably should not make the investment attempting to make a high return quickly.

If you have any high interest rate debt reducing or eliminating that debt is likely to be your best choice.

Take the time and effort to learn about any investment you are considering before actually investing a significant amount of money.

Buy high quality treasury bonds.

You're right to avoid the stock market - you haven't any idea what you're doing.

Nowhere.
