I have a similar concern. First, I forgot to move nondeductible (after tax) portion in my rollover IRA from 401K to Roth in 2017. Also TurboTax never asked me to file Form 8606 in 2017. Then in 2019, I took a withdrawal, hoping that it would be non-taxable. For 2019 tax filing, what should be my correct approach. I am not sure and aslo I don't understand what TurboTax is guiding me.
