Hello there, @mullersbakehouse.
Thanks for visiting the Community. To clarify, QuickBooks Online (QBO) only supports sales taxes and payroll taxes.
The only version that supports tax deductions is QuickBooks Self-Employed (QBSE)where you can claim self-employment expenses. For more information, refer to this article:Self-Employed expenses You can claim. It contains a run-down on the available categories to sort your transactions.
Here are other resources for your future reference: QuickBooks Self-Employed Overview. It helps you learn about what you can do in QBSE.
I'm always around here to answer if you have more questions. Have a great day.
