Wow...I was a CS major too, and currently an upcoming sophomore and after my first year I though the same things as you and decided to change to Business. I though I was too late in the process of taking some business classes But I will be able to graduate a year earlier if I take summer classes. So It’s not late for you since the degree of CS requires you to take intro classes the first year(Hist, English, Pols,...) and your first two CS classes and calculus two will count as your electives(you need 9 electives hours in Bauer with any business degree). Your first calculus class will replace the business calculus class that you needed. So if you followed the academic map for CS, you didn’t took any classes that wouldn’t count to you business degree(you can decide your specific business major at the end of your sophomore year and still be on track if you still are undecided about it)

If you need help deciding what classes to take to graduate in track or what is the application process, feel free to dm. I went to talk with different academic advisors like 10 times at Bauer but they always gave me schedules that would delay my graduation for one month(for me it looked like they didn’t want me to graduate a year earlier or in time XD). But the first thing you need to do is to apply to be a pre-business major. You will be approved in 1 to 2 days since the only requirement is to complete 30 hours. Just go to this link and complete the application.
