@blueberriesforsal is almost certainly correct - the pathway for you to leverage rowing as a recruiting tool is very unrealistic. While rowing generally starts later than other sports, spring of your sophomore year gives you less than a year to be competitive with other athletes interested in a “top school.”
That said, Dallas United Crew is a well-respected program, and there is no reason not to start out with their next Learn to Row program this Spring, both because rowing is a great sport to learn, and because some basic skills building will allow you to get early metrics. Unfortunately it looks like you missed one that started this past Monday. Call them and see what your options could be.
The good part is that rowing recruiting is very metrics-driven: the bad part mostly is that 5’4" and 132lbs isn’t a great set of metrics for either lightweight or openweight women’s rowing teams. That said, if you are strong as heck and can pull an excellent erg score after learning the basics in a Learn to Row class, it’s not impossible to overcome. It’s happened, though usually for athletes transitioning from another sport, most commonly Swimming.
I’ve seen that parents often think crew is a cheat code to elite school admissions - I can say with confidence that it is very much not that. Grades and test scores need to be in the admissible range, and even more, the athletes who do make that transition have generally been working for years at it, have built some combination of unbelievable strength and strong mechanics, and have a deep love for the sport (and the training expectations, which are beyond significant).
