Re: I already started my adwords where can see this ad words
Hello and welcome,
I think you mean here that you want to see your ads on Google search. Let me know if that's not the case.
Google provides advertisers with a tool call Ad Preview Tool which you can use to see real time results of your ads. Use this tool to check for the results and I won't encourage you to look for the results on live searches because doing that will affect your impressions, CTR etc...Below link will assist you more on this.
Hope that helps!
