Colleges see all your attempts, but they're not going to penalize you for retaking. The improvement from 1320 to 1510 actually tells a good story - it shows persistence and that you responded well to feedback. Admissions folks understand that standardized tests aren't a perfect snapshot of intelligence on day one.
As others mentioned, many schools use superscoring anyway, so they're essentially combining your best sections across attempts. Even schools that don't officially superscore will typically focus on that 1510 when evaluating you. The narrative of improvement matters way more than the number of tries. If anything, retaking once or twice shows you're serious about doing well, not that you're struggling with the material. You're fine - that final score is solid, and your upward trajectory is actually a plus.
