I was able to find the recurring charges reminder on left had side:

Recurring Transactions

Reminder List - Click that on top right.

Edit and Create

The issue now, is that the reminder doesn't drop off, once you've completed the task.

It still show that you need to create the bill, when you already have.

You then have to click the drop down arrow and click "skip".

I've ALWAYS from the beginning of Quickbooks coming out, been a huge fan and supporter.  I work on both QBO and Desktop.  I wasn't crazy about online, but slowly became a fan.  But now, the Quickbooks service is horrible and they have changed things (fine), but not for the better.  For the first time in 30 years, I'm seriously considering a different accounting software.

I've been promised a call back and/ or a fix on this issue since July 2023, and nothing......
