I sent it back to the same address from where I received the USDT amount, but it never came back
Where did you send your USDT? Is it from an exchange? What’s the name of that platform?
Yes, It is Bitmax.io.
And the address from and to is: THJ862u6NXSqgvjAV8KdnrAEAcXiEYD3Cw and I used Chain Type TRC20
