You have until 11:59pm local time on October 17, 2022 to e-file the 2021 tax return.
If the tax return is rejected TurboTax normally gives at least 5 days after rejection to e-file the corrected tax return. After that extended date the 2021 tax return can only be printed and mailed.
The TurboTax online editions are normally available until the end of October so they can be used to print the 2021 tax return.
