Yes, it will be automatically denied, at least the original claim. You will have to appeal and prove what you were paid for, basically, the last 18 months, and it could take several months.
The problem will be, even if you WERE properly classified as an employee, the "employer" does not have to take into consideration your personal situation when scheduling your hours. Quitting because you have a personal situation that does not "allow" you to work the hours required by the employer almost never is a qualifying reason to quit and still receive UI benefits. Again, this would be true even if you were not "improperly classified as an IC".
