setting up recurring meetings

Every time I set up a meeting or a recurring meeting, a choice of calendars occurs.  Right now, I do not want to use any online calendar.  However, if I cancel this process, my meetings are not set up.  How do I set up meetings without being required to register or use a calendar online?   

As a side note, the system warns me that Zoom will be able to download sensitive data from the calendar source when we choose it.  It also says I can manage what info in my account.  I just don't want to go to all that extra time and energy, especially when I do not and do not want to use an online calendar.  Can someone assist me with these concerns, please?
