Get your taxes done using TurboTax

@jinrui1130 Not sure why you are posting to this old thread about e-filing a 2018 return.   The only tax year that can be e-filed is 2021.   No other year can be e-filed.   If you are trying to e-file a 2021 return and the AGI is causing rejections, try using zero instead of your AGI.
