Welcome to Community, @smr360! 

I see that you're unable to import you're transaction due to an error in your sales tax. Let me help you on how to fix this concern.

Here's how: 

• Turn on your Sales tax:
  
  
  1. Go to Sales tax.
  2. Click Use Automatic Sales Tax.
      
• In QuickBooks, you can only import specific fields. Thus, you need to remove the tax column on your spreadsheet and then Import. 
• If you don't have a sales tax column in your spreadsheet yet the issue persists, I recommend you use your private browser to import your transactions. 

Here are some shortcut keys that route you to your private browser: 

• Google Chrome, Windows, Linux, and ChromeOS: Ctrl + Shift + N. 
• Mac: ⌘ + Shift + N

You can visit this link for future reference if you have already imported your transactions: 

• Categorize online bank transactions
• Match online bank transactions 

Feel free to reply if you have any other concerns. Enjoy your day!
