It looks like that I cannot e-file a Form 1040, because the taxable income is $0. However, on this Form 1040, there's earned income from Schedule C and unemployment benefits that are reported. In addition, the return shows a refund due that resulted from EITC, CTC and taxes paid on form 1099-G (unemployment). Can someone shed some light why this return cannot be e-filed just because the AGI has been absorbed by the standard deduction? Thank you.
