Yes, there is a reason the return must be mailed. This is the tax return for my 94-year-old mother-in-law. She does not have a drivers license or other form of ID, which is required if the Alabama return is to be e-filed, meaning that paper is the only option. When I was completing the form, I initially tried to e-File, but TurboTax had me change it to paper for the state return. (I was able to e-File the federal return without trouble.)
