Active Duty Enlisted, Free Service

I am E6 Active Duty and trying to file my taxes for free but I keep getting prompted to pay $178. This is the first time I have experienced this issue since joining the military in 2014. I read through some forums/Q&A on the turbotax website and tried some of the proposed solutions (ensuring EIN correctly written, selecting Active Military Duty, deleting the W-2 and re-entering it) but none work. Please help, Thank you.
