How can I remove the advertising pop-ups

You can't.  They are there for the long haul. 

Someone will be along shortly to make it out like it's not that bad, and you can just "click the X or "No Thanks" and it goes away. (Not telling you that it always comes RIGHT back. 

You can try using a pop-up blocker.  Sometimes that helps. 

Good luck.  

As of the moment, there's no way to completely disable ads from popping up, ctomblin.

As a workaround, you can enable the pop-up blocker in your browser. Here's how:

1. Select the lock icon to the left of the address bar.
2. Click Site settings (Google Chrome) or Permission for this site (Mozilla browser).
3. Hover to the Pop-ups and redirects section, and hit Block from the drop-down menu.

For Safari:

1. Open your Safari browser.
2. Select Safari, then click Preferences.
3. Select Websites at the top
4. Click Pop-up Windows on the left sidebar
5. Then hit Block in the pop-up menu for the website.

How dare Intuit spam its paying customers with ads ALL DAY LONG!! Who else does this? No one. I am a paying customer and dont want to see these ads. Dismissing them does nothing because as soon as I return to the same screen they re-appear. ALL DAY LONG. Every day, all day, dozens and dozens of times a day. This is outrageous and completely unacceptable. Yet one more example proving that the Intuit developers and decision makers don't actually use their own software or listen to people who do. If they did they would not publish such garbage software. 

(Yes I turned on Chrome's pop up blocker for QBO's site and also installed my own. Neither eliminated these offensive, annoying and never ending ads for products I'm not interested in and have already told Intuit I'm not interested in them by dismissing them the first 100 times.)

I should not have to find a way to turn off an add posing as a tutorial. This should not pop up every time I try to do something I do on a daily basis, I clearly know what I am doing....
