I am having the same problem. I e-filed my NYS tax return and on the instruction cover sheet it says my taxes are not finished until all required steps are completed. The required step is to sign and date E-File Signature Authorization within 1 day of acceptance. When I logged in turbotax it does not allow me to sign because the tax return was transmitted. I called TurboTax support but didn't really get an answer to my question.
