Thanks for reaching out to us about this syncing issue with Connect with Square, @Hedg.
QuickBooks serves as a receiving channel for your Square transactions and the way these entries are downloaded depends on the connected app. You'll need to consult Square directly to get help with data transfers to our software.
If the tax information are off, trying a different application would work as suggested by Fiat Lux - ASIA. We have lots of tools you can choose from in our apps site. Here's the link to our site: https://quickbooks.intuit.com/app/apps/home
We also have another forum called Intuit Developers, where you can find engineers who can recommend third-party applications for you to use. In this website, you can connect with people who can help with app integrations, take part in software developments and innovate business tools for QuickBooks.
