Hello @kflagg,

I'm glad  to hear that you've located the left navigation panel. The reason that you may not be seeing Transactions is that some options vary based on how the account was set up. 

Just to clarify, do you see an option on the left marked as Accounting?  In some accounts, this replaces the option for Transactions. If so, you would select Accounting, then Chart of Accounts, and follow the steps provided by my colleagues to make the account active.

It's my priority that you're able to make the account active again and I am including a visual guide for re-activating an account named Equipment Rental:

The following article contains additional information about this process: Delete or Make an Account Inactive.

Since you reference that you're not seeing the account in the Chart of Accounts, is it possible that the name may have been changed or account merged? The Audit Log is a tool that can be used to look for changes and activity within an account and I'm including an article with additional insight on it: View Audit Logs in QuickBooks Online.

Lastly, this isn't the impression that I'd like for you to be left with. The updates and changes to QuickBooks Online are largely the results of feedback provided by users. I'm going to submit feedback on my side for you based on this interaction. The software is constantly evolving based on feedback and I can assure you that your voice matters.

Please don't hesitate to let me know if I can be of additional assistance. Wishing you and your business continued success.
