How can i see all the checks to us from a specific client?

Thanks for posting the Community space, @hbennett.

There are two ways on how to see the checks created for a specific client in QuickBooks. I'll show you how;

First, is by going to the Expenses menu and filter the transaction to check and the client's name:

1. Go to the Expenses menu then click Expenses.
2. Tap the Filter drop-down.
3. Under Type choose Check.
4. In the Payee drop-down choose the client's name.
5. Click Apply.

Next is to run the Check Detail report. This will generate the list of checks that you've issued for your client. Here's how:

1. Click Reports on the left navigation pane.
2. In the Go to report search field, type in Check Detail.
3. Click Customize in the top right-hand corner. 
4. Filter the dates under the Report period.
5. Click the Filter drop-down.
6. Click the drop-down next to Transaction Type and place a check-mark next to Check.
7. Click the drop-down next to Name and choose the name of your client.
8. Hit Run Report.
