I am Massachusetts resident and I replaced my septic system in 2018, and how do I file the schedule SC for repair or replace a failed septic system credit?

There is a form at Mass Dept of Revenue website  Schedule SC   Septic Credit for repairing or replacing a failed cesspool or septic system.   how do I file it at Turbo tax? I can't find the form at Turbo tax.  Thank you for your help
