No, you can't swap USDT for USDC with matcha mint.

I tried to withdraw some USDT and it only supported USDT on the chain. It's not allowed to withdraw USDT from other chains like TRON or ETH. I used TFX to buy USDT and want to convert it to Polygon USD. Is this platform only supporting USDT withdrawal or am I doing something wrong? Any expert could help me with this please?
