Accused of cheating on online exams
First thing you may want to do now is to read and understand the policies of your university related to how academic misconduct cases are processed. You may receive support from Student Support or similarly called unit in your university.

Typically the process goes like this: professors suspect a group of students of academic misconduct and file forms to the relevant person (responsible for academic misconduct).  They quickly go through and decide which cases to dismiss instantly, and which to pass on to the misconduct committee panel. 

If your case goes to the panel, you will be asked to come and respond to the evidence. Normally, it is sufficient to provide a brief explanation like the one you provided in you question here.  A sensible panel will then dismiss the case without a penalty.
