Other questions

I appreciate you following up with me, @PattyLU. 

I can assure you that inactive accounts do not count against usage limits. When selecting the drop-down triangle in the Action column, the option states "Make inactive (reduces usage)." I've included a second video to highlight this option:

Additionally, the original video shows the usage for the Chart of Accounts goes from 44 to 43 after the account is made inactive. 

While I realize that you may not wish to try this in your normal account and suggest trying the QuickBooks Online Sample Company. You can access this resource by visiting the following link: QuickBooks Online Test Drive.

If you're seeing any behavior aside from this, please let me know so I can help you get to the bottom of the issue

I'll be keeping an eye out on this post should you have any questions. Hope you have a wonderful weekend.
