Wrong SAT Taken times

I just made a stupid mistake today… I wrote in my common app that I have taken the SAT three times and I will take another one, but in fact I have only taken two times and have sent all my scores to Cornell (who asks for all sat scores)…

Since I can’t fix common app, should I send Cornell admission office an email to explain this? If it’s minor mistakes I won’t bother, but sat scores are about academic integrity. But at the same time I’m afraid that the officers would have a bad impression on me because I entered something wrong on the common app (I checked it twice, tho)

A reminder: on the preview pdf common app will show sat taken times, but on the website they just ask you: how many sat do you wish to report". This information is slightly misleading…
