I am trying to file my Federal and NY State amendment for 2017. I know I have to file my federal amendment by mail but NY amendment is required to be efiled. Turbotax takes me through all the steps but when its time to file - it cant seem to do it and says that efile window closed on October 15th 2018. I understand that October 15th 2018 was efile window for your taxes, but not for your amendments. Any ideas?
