Hello there, evette!
You'll be glad to know that you can pull up the Transaction List on your Expenses page, and sort it by vendor by clicking on the PAYEE column header. You can print and export from there.
I've attached a screenshot below for your visual reference.
To add, I've found an article that you might also find handy: Know More About the Expenses Page.
Feel free to leave a comment below if you need any other help. Have a blissful day!
