"Subsequently returned" means that the check was not paid by the bank on which it was drawn, and it was returned to the bank that cashed it or took it for deposit, marked "unpaid." The check may have been returned for one or more of a long list of reasons. There may not have been sufficient available funds in the account; the bank may not have recognized the account; the account may have been closed; the signature may not have matched the bank's signature card; the date could have been a problem, and a lot of other possible problems. The reason for the return should be marked on the face of the check.
