I appreciate you for joining this thread, midtownnow.

At this time, the option to change a transaction's accounting method is not yet available. You'll want to delete and recreate them just like what my colleague MarsStephanieL mentioned.

I understand the convenience it can bring being able to enjoy the said feature. While we continue making improvements with the product, I want you to be updated to the latest future release in QuickBooks by visiting this website: QuickBooks Updates: New QuickBooks Accounting Software Updates.

I've also got you this article to learn more about how QuickBooks Apps work: QuickBooks App for Windows and Mac: General support.

You can always get back to me for more questions, Take care and have a wonderful day ahead!
