Hi, I'm new to ProSeries this year.  I'm working on a fiscal year C Corp that was extended, so we are just now filing the original 2019 return.  I completed the return and the program allowed me to select the IL return to e-file.  I received confirmation that Federal 1120 e-filed, but received a State-901 reject error for the IL return.  Error message said the state can't e-file before the Federal and to re-submit. Now that Federal has accepted I have attempted to re e-file IL but now I'm getting errors that the IL fails to convert and upload to e-file center.  Since I'm new I'm not sure if I have done something wrong that can be corrected, or if this is a indirect way for the program to tell me that e-filing the IL Form 1120 is never going to work and I should mail it in.  Any advice?
