How do you use “I did+？” there is a example sentence in my class book： I did my homework I didnt do laundry Iwant to speak more like this sentence so I said， I did exercise，but it's wrong，isn't it？ I did jelly. I did shower. I did soup. Are those right? what else words that it can following the “ I did ”？ Thank you！

Asking the way I met a young man who asked the way before two years ago. He was not a traveller so he didn't has a map.Thank you very much,he has a address on his cellphone.Then he showed this text for me. I knew where was he wanted to go to,but I didn't know how to tell him. I felt upset.
