Hello there, @eyenstein.
I'll help you sort this out. A few times when lots of processes happening to a browser, this will make the stored cache loaded with internet files.
Thus, you can use a private or incognito browser to isolate this issue. Open a browser and press Ctrl + Shift + N (Google Chrome), Ctrl + Shift + P (Firefox) or Command + Shift + N (Mac browsers).
From there, open the Intuit Account Management portal link and turn off the 2-factor authenticator. Then switch it on again. Once done you can then login to your QuickBooks Online/Self-Employed account to test the feature.
If this fixes this issue, clear your regular browser's cache to load new files or pieces of data. It will also boost your browsing experience.
Alternatively, you can use different browsers for Intuit Account Management portal and QuickBooks Online/Self-Employed like for example running Intuit Account Management on Google Chrome and run QuickBooks Online/ Self-Employed in Firefox to check if this a browser issue.
I've added an article for this feature to enable and eliminate: Turn on or turn off two-step verification.
