Narrative:
I was advised by lead 'C' check mechanic that an improper carryover of a 'C' check routine task card had happened on aircraft. I had approved the carryover deferral in the maintenance system. Being very new to this computer system; I did not realize the mistake I was making; because the system gave the options to complete the deferral with no problems. I believe the system should not give you the options to defer a routine task card. This is very confusing to a new user and should be fixed in the system. Since the incident I have reviewed the 'C' check carryover system. The task card will be re-issued.
