Should I submit outside transcripts?

I took a Spanish class at an online school the summer before my senior year, and my guidance counselor said that it won’t go on my official high school transcript.

I’m debating whether or not I should send the online school transcript to colleges because it is really expensive ($15 each). And there’s only one course on the transcript.

I’m wondering would only two years of foreign language hurt my application if I have a 5 on an AP language exam of another language?

Thanks for your help in advance.
