Hello. I have attempted to file by mail multiple times. Your system is requiring me to e-file my TN return, which is ridiculous since TN does not have state taxes.

Just as a heads up - you posted this question into a general group chat. The people who have the ability to answer these questions are other regular tax filers like yourself. 

I would try contacting someone actually from TurboTax instead maybe via phone or email. I'm sure they have a "Contact Us" on their website. Hope this helps!
