I'm literally going through the same thing and it's never happened before. It says the error code is AL2019StandardDed and my email explanation says it's because :AL 2019 Standard Deduction - Your Alabama return was rejected due to product updates relating to the Standard Deduction calculation. This update has been released. Re-transmit the return.
but when I went to fix it, it literally said it was ready to file and submit again. This is my THIRD time resubmitting it.
