Im not a programmer and just doing a project and my rx, tx and L are turned on but when i upload sketch it doesn't upload and my arduino heats up and i cant reset my arduino uno aswell but my laptop still reads when i plug the arduino in

i tried to connect a 12v dc to its 5v pin and i think it was the reason

My Rx, tx, and l is on but not uploading a sketch
