The return was mailed not E-Filed for 2017. Not sure if that's the reason. Have refiled the return, still being rejected.
Try zero, if not, print and mail your return. Don't forget to also print and mail your state return if needed; in most cases, your state return is not transmitted if your federal return is rejected. Make sure to check the status of your state return.
Some e-file rejections just can't be fixed even if your info is correct.
