I Think I damaged my module LED&Buzzer

So I did the LED project and it worked, then it was said to try with other pins so I inserted the positive side of LED(the resistor leg) in A0, TX,RX pins. When I put it back in 0 pin it stopped working and I think I damaged my module. The buzzer didn’t work as well. What do I do?
Please Help.
