When a check does not appear on your bank statement because the payee has not yet cashed the check, it is called a(n):

An outstanding check is a check that has been written and recorded in the issuer's accounting records but has not yet been cleared or cashed by the bank. This means the payee has not yet presented the check for payment, resulting in it not appearing on the bank statement. It is important to track outstanding checks for accurate financial management since they represent a liability that will need to be accounted for when the payee eventually cashes the check.

A voided check refers to a check that has been marked as invalid, typically because it was written incorrectly or not intended to be used. An e-check is an electronic version of a paper check, used for transferring funds electronically, and does not pertain to the situation described. A non-sufficient funds check occurs when there are insufficient funds in the account to cover the amount of the check, which doesn't apply to checks that simply haven't been cashed yet.
