Hi there, @cgutierrez1. I am glad you chose QuickBooks Online (QBO) as your new partner in managing your business finances.
Speaking on your tax totals, QBO doesn't have the option to adjust the difference originated from other accounting software since our system is only dependent on the data you transferred or shared with it.
If you wish to make changes before transferring your tax data, I recommend performing this in your previous software or contacting their support team to guide you on editing the tax total before migrating it to QuickBooks.
Since you're new to QuickBooks, you can visit this article for additional guidance in setting up your account: Get started with QuickBooks Online.
I am pleased to have you here. You can always return here for additional questions in setting up your transactions and information in our software.
