I'm glad you requested our assistance here, @nathaniel3.

Let's collaborate to fix the error you're experiencing.

An issue with the browser is frequently the root of the error: An application error has occurred while processing your request: -90.

Since logging into your account through a private browser or incognito window prevents data from being stored in the cache, it is a place to start your initial troubleshooting. 

You can refer to the following keyboard shortcuts below:

• Google Chrome: press Ctrl + Shift + N  
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Shift + N

If you are using Google Chrome, follow the steps below to clear the cache:

1. Choose the More icon from the top right corner.
2. Select Settings.
3. Pick Security and privacy.
4. Pick Other Site Data and Cookies.
5. Select See all site data and cookies.
6. To find Intuit cookies, type "intuit" into the search box.
7. Select the Trash Can icon or Remove all shown.
8. For the changes to take effect, restart Google Chrome.
