Unable to withdraw

Because I encountered a black screen gold investment online fraud of 300000 yuan in early April, and was reminded by another netizen that I did not immediately deposit any more money. This friend told me that this is the first time that a legitimate platform can deposit and withdraw money without going through customer service. $309 was profitable, $49 was successfully deposited, and $358 was deposited without any handling fees. Later, the deposit amount was $4586, which was $6800 from a friend at home, totaling $11386 in profit. When 3567 requested a bank deposit But they said they need to pay taxes of $3080, which is almost all my principal out of a total of 20.6%. Why do I need to pay these taxes and cannot contribute? Is it okay to ask for a smaller amount? He said that no matter how much money needs to be paid, the tax must be paid in before the money can be paid
