Hi there, @moonslice2.

Yes, QuickBooks Desktop 2019 doesn't require Internet Explorer when logging into your company file. 

You don't have to worry about browser requirements since the product you're using doesn't require internet access to log in. Just make sure to use the correct username and password when opening your file. 

Moreover, for supported versions of QBDT such as 2021 and above, the product uses Google Chrome as a new default browser to access your Intuit account log-in. 

Also, our Help articles might have something that can help you with your QuickBooks concerns, too. Just make sure that the topic is set as "QuickBooks Desktop" to browse for related posts.

I'm just a reply away if you have other questions with the QuickBooks Desktop. Just add the details of your concerns in this thread and I'll help you out.
