this doesn't show up in my report....has it changed?  I can't seem to run any report to show untagged transactions . 

It's great to see you joining in on this thread, sep32. Tracking untagged entries is important to see which transactions are added to your data. I'm here to provide information to help you run the report you need.

You may consider running the Transaction List by Customer report to review all untagged transactions. This will enable the data entered on your account to show when pulling up the record. To do this:

1. Go to Reports and enter Transaction List by Customer report from the search icon.
2. Set Group by option to None and review the correct reporting period.
3. See all transactions that aren't been added with tags.

In addition to that, you can review and see all untagged transactions from the Tags section under the Gear icon. Refer to these steps to track these entries:

1. Go to the Gear icon and select Tags.
2. Click the See all untagged transactions link.
3. Select all transactions to which you will be adding tags.
4. Click Update tags, then select Add tags.
5. Type in the tag that you want to assign. Once done, click Apply.

Furthermore, I've included this reference that may help you memorize the customization applied to your reports: Memorize reports in QuickBooks Online.
