You cannot file a 2021 return any longer thru the TT program ... you will have to paper file it.
Some professionals can still efile 2021return HOWEVER even they cannot do so now as the IRS has shut down efiling for the switch to the 2022 program. When the 2022 efile season opens sometime in January some tax pros will be able to efile 2020, 2021 & 2022 returns but you will not be able to do so thru the TT system.
