It's nice to have you as a member of the Community. I'd be glad to help you with generating a report that lists all of the checks that you've issued, including payroll.
One option that you have is to generate a Check Detail report, which will list checks, payroll checks, and expenses. If you wish to exclude the expenses and only have checks and payroll checks, here's how:

Select Run Report.
