Hi there, @22780870.
We want to ensure correct taxes are calculated so accurate amounts are paid and filed to the IRS. QuickBooks will calculate taxes depends on the preferences that you set up.
To check the calculation of your taxes, I'd suggest contacting our QuickBooks Online Support Team. They can do screen-sharing and review your account to know the root cause of the issue.
Also, they can process an adjustment if they found out that there's a discrepancy with the calculation of your taxes.
You can reach out to our customer support through this link: Contact the QuickBooks Online Customer Support team.
