A green message displays at the top of the form area to indicate that the file is locked.
If the return was locked using a previous version of the software, you can click the Preview changes button to see a list of calculation changes that would apply if you unlock the file.
Lock a File
Go to the Security menu and click Lock File.
If you have transmitted all required returns and forms in the file, TaxCycle will prompt you to lock the return. Click the Lock button in the message. Alternatively, you can configure TaxCycle to lock the file automatically in T1, T2, T3 and T5013 files after transmitting all the required returns and forms. To learn how, see the Automatic File Locking help topic.
