Thanks for joining the thread and welcome to the Community, @mmcis.
At the moment, the ability to move the help window isn't available as mentiioned above, but I do think this is a great idea so I'll also submit your idea to our Product Development Team for possible implementation. We take your feedback seriously, as it's what helps us grow, so we appreciate it very much.
Since you mentioned you're new to QuickBooks Online, I recommend checking out our awesome video tutorials.
Feel free to come back to the Community if you have any questions, we're here to ensure your success. Have a good one!
