Hello there, BenTam,

As per my colleague Sophia mentioned, QB generate the numbers per transaction type.

There's a possibility that the report is filtered to only show payment transactions. If that's the case, the check number will show on the Num column.

Let's click the Customize Report button to check the filters. Then, run the report again. You can also create a memorized report to save it for future use.

I'll be here if you need more help.
