Hello 5star22, You can run an audit log report and in the events section change that to deleted and voided events that will show all voided transactions. If you want to see invoices only you can go to sales>all sales > use the filter to filter the transactions to invoices and the date you want and apply. Then in the small cog within the page above the word action make sure status is ticked. Then you can click on the staus column and it will sort alphabetically so if click the arrow once it should start at all the voided invoices. You could if you wanted on that page then export it to excel so you could look clearly at them.
