But you best hurry on 2017.... the witching hour is fast approaching (7 days...)

I think you can file until the filing season is closed. Once the 2020 return is added to MeF, then the 2017 twitches away.

Good to know,George.    I guess....I have officially sworn off doing delinquent returns (until I change my mind)
