Hello, deedee1.

As a user myself, I would also like an option to hide ads forever on a software I paid for. While ads may show offers you're interested with, I prefer a minimalistic and manual approach on other offerings. 

That said, I have some information regarding the options in hiding the new ad. 

At this time, you can only select Maybe later or Try Now on the new ad. So, we're unable to completely remove it once and for all. 

If you haven't already done it yet, I do recommend sending feedback to our developers to have an option to completely remove ads. They'll take a look at your suggestion and might consider it for future improvements. 

Simply go to the Help menu, hover on Send Feedback Online, then select Product Suggestion. 

With that out of the way, do you help managing your customer deposits? You might find this article helpful: Deposit payments into the Undeposited Funds account in QuickBooks Desktop.

I still want to hear you out if you have other concerns regarding QuickBooks Desktop's features. Did you encounter any obstacles while managing your lists, reports and entries? Let me know and I'll help you out.
