Great day, @Comfortcafeomaha.
Let me help you clear things out. Mapping an item will depend on its detail type.
Since it is a tax type, the account or category you select for a transaction will determine where it applies on your tax forms, typically Schedule C.
For instance, if you choose Advertising/Promotional under Detail Type when creating a new item, the expense will appear under Advertising on your QuickBooks Income Tax page and will appear on Line 8 of your Schedule C.
Feel free to read this article for more details: Learn where QuickBooks Online detail types appear on your tax forms.
We'll be always here once additional questions about item mapping pop up in your mind. Keep safe.
