Thank you for trying the steps provided by my colleague above, @jbuhlman.
I'm here to provide you with further information to help you signing-in into your account successfully.
QuickBooks Self-Employed (QBSE) works well with Google Chrome version 78 or newer. Since you're still having trouble even after using an incognito window, try logging in to your QBSE using other supported browsers (Firefox, Safari, and Microsoft Edge).
If you're still having trouble logging in using other supported browsers, I suggest reaching out to our Customer Support team. They can check your account in a secure environment, isolate the error you're and help you in resolving it.
Here's how to reach them:
- Go to the Assistant menu from the top bar.
- Enter Talk to a human and select I still need a human.
- You'll now be provided with support options that are available at that time.
You can check this article for more information about the different types of support we offer and their availability: Contact QuickBooks Self-Employed Support.
Stay in touch if you have additional concerns logging in to the account by leaving a comment below. I'm always glad to help in any way I can. Have a great rest of the day!
