You can run a Profit and Loss report to view a list of accounts associated with transactions marked as disallowable, Info2172.
Please know that QuickBooks Self-Employed (QBSE) automatically determines whether an expense is allowable based on your tax profile, so you don't have to adjust or classify them manually.
Here's how you can run a report:
- Go to Reports.
- Click Profit and loss and choose the date you want to run.
- Hit View.

Feel free to explore this article to understand better which expenses are considered allowable and which are disallowable: Allowable and disallowable expenses.
Additionally, you can check out these articles in case you need guidance on categorizing transactions and using rules to manage them in QBSE: Create rules to speed up reviews in QuickBooks Self-Employed.
