Hey! Does your school offer summer school for credits? because if they do, you can most likely switch that AP calc grade out. Or, you can try to explain why you got this grade in your college apps (mental health, other problems.) GPA rising can be done by taking AP courses (since they add more weight) and yes, most likely it will help you application. You can choose what best works for you and it also depends on the college you want to go to. Try to talk to your counselor about retaking a course. Also, amazing job! taking AP calc in freshmen year is AMAZING.
