Thanks for your response. I forgot to mention that I already confirmed that my dad didn't file with TurboTax online at all. His paper records only have tax filing up to 2012 ( he passed away in June, 2020). Not sure whether he even filed tax return after 2012. I know IRS has records. But I would hate to alert their auditing. I'm trying to find some other ways to confirm when was was his last year that he filed tax.
