I am simply trying to find a check by # and cannot.
A warm welcome from the Community, @animaldoc.
With QuickBooks Desktop, you can use the Simple Find feature to do a quick search using the check number.
The system will provide the list of transactions matching the check no. Click the check you want to see and hit the Go To button.
That should get you pointed in the right direction.
Let me know if this works for you. Take care and have a great day!
