We don't pay, but it would have been worth it in 2020.
Once the state gets the forms, they get scanned. That year, some form didn't scan right, so it was kicked out and our return reworked without it. We got an automated revision and a deadline. We resent the form, but since no one was in the office due to the pandemic, it apparently just sat until after the deadline passed, which resulted in another automated form.
We eventually, finally, got someone on the phone, and she agreed that our return was correct and closed the case, but dang...
It seems very counter intuitive that states don't encourage/offer free online submissions.
