Hello there, @BigNateRadio.
I appreciate you testing out some solutions in fixing the application error. Let's perform some other troubleshooting steps so we can successfully update your contact details.
The An application error has occurred while processing your request: -90 and -1 is typically caused when updating information using non-Admin credentials. You will have to use the Admin login to get past the error.
Another option is to open and log into this link: accounts.intuit.com.
I'm confident that this information will help you get back to business.
Keep me posted if you have other concerns. Have a great rest of your day!
