How do I know if my USDT is ERC20 or TRC20?

Hello, I'm trying to figure out which type of USDT token I have in my wallet. I've heard there's ERC20 and TRC20 versions, but I'm not sure how to distinguish between them. Could you help me out with this? Is there a specific way to check the token type within my wallet or on any blockchain explorer? I'm a bit new to this and would appreciate any guidance you can provide.
