Can I use an Indonesian bought iPhone 13 in the US with aT-Mobile sim?

If its unlocked, yes.

If its locked to an Indonesian carrier, you will need to contact them to either get it unlocked or if this is only a temporary vacation type thing, get a Roaming plan form them so you don't need to use a T-Mobile sim.

You'll need to contact the carrier in Indonesia...
