Unable to log in all of a sudden. Says my account is invalid

Hello, Beth! It's great to see you make your first post here in the Community! Accessing your account is essential for tracking your daily transactions. You can count on me to guide you through the troubleshooting, ensuring you’re back to business in no time.

One possible reason you're unable to log in could be that your browser has accumulated too many cached files. QuickBooks relies on the browser's cache to function efficiently, so clearing any outdated files can help improve your viewing experience and overall system performance.

Let's start troubleshooting by pulling up your QuickBooks Self-Employed (QBSE) account using a private browser (incognito). Here are the keyboard shortcuts below:

• Press Ctrl + Shift + N (Google Chrome)
• Ctrl + Shift + P (Firefox)
• Control + Option + P (Safari)

Once signed in, go to the Sales or Expenses menu to look for the payment and their standing.

If you're able to do so, return to your default browser and clear its cache (The article is intended for QuickBooks Online but is also applicable to QBSE). After that, you can restart your browser and log back into your QBSE account to refresh the system.

However, if this matter continues, I recommend clicking the browser's Refresh icon (please see the screenshot below) or using other supported browsers. 

Moreover, if the issue continues, I'd recommend checking out this article for more sign-in tips to help you retrieve your account: Recover your Intuit Account.
