I know why your QuickBooks Self-Employed (QBSE) app no longer works, anahata. I'll discuss the details below.
Starting March 24, 2024, the QBSE app will not be accessible for download. I'd recommend using the web or mobile web versions of the product to access your account, as they offer similar features to the app.
However, you can redownload the app by locating it in your app store's account history. Just make sure to use the same app store account that you used before to download the app. For instructions, please refer to any of the links below:
For more details about the availability of the QBSE app, please see this article: What happened to the QuickBooks Self-Employed mobile app?
Also, I'd recommend categorizing your transactions to organize your financial data and allocate them on the correct line of your Schedule C.
Leave a comment below if you have additional questions about the QBSE app and concerns about managing your self-employed transactions. I'll be willing to lend a hand. Keep safe, and have a good day.
