Please let me know if you have found a solution to get the return e-filed. I am also having the same issue trying to e-file an amended California return. I have tried the "uncheck error checking" but I am still getting e-file reject.
@marv1123 You might have a specific error with your return that is different from my error message above. I'm sure someone can help if you share your error message. The unchecking method solved it for me.
