Hi there, Spaulding. The Transaction Report in QuickBooks Online shows all transactions for an account by default, but you can filter it to display specific checks. 

To create a transaction report for a check you wrote, let's pull up the Profit and Loss report. Here are the steps to follow:

1. Navigate to the Reports menu and choose Standard Reports.
2. Select the Profit and Loss, then click the Total for Expenses amount.
3. Set your desired reporting period and hit Filter.
4. Change the Distribution account to Transaction type.
5. Set to Equals, and select Check.
6. Click the + Add another filter area and choose Vendor name.
7. Set to Equals and select your preferred person.
    

You can customize the report to show additional details as needed.

To stay on top of things, you can connect with our QuickBooks Live Expert Assisted team. They can recommend additional reports based on your specific financial management needs.
