If you used the online program and the return was rejected for an incorrect IP PIN number (you must use the new one issued in January 2022 & not the one you had for the 2020 return) then you can print, ink sign and mail in the return. There is no refunds of the ONLINE fees once you paid them. If you want to try filing a different way you can simply walk away from the TT program since the return was rejected.
