In the code I$\text{'}$m providing, I have a working version of TicTacToe from ChatGPT. Runs fine, but it's not the best programming structure. You will see several comments in all capitals in the code. You need to leave these. Then do what is indicated by the comment. In some, you will be changing code and in others, you will answer in your own comment underneath mine.
