Hello and thank you for your inquiry. The cancel checks written against your account are on the last page(s) of your bank statement. To access your statements logon to usaa.com> select your name> My Documents> Select the appropriate statement. Thank you! - Darrell
Another option: You can also go "My USAA" click on the particular account that you wrote the check against>>then click on the account>>click on the check numbe(icon)>>print option. It will print front and back on one sheet.
I use it to print to pdf so I can attach it to transactions in my Quicken software.
