Does anyone have any experience with the state of IL stating that they could not verify withholding via electronic W-2 and 1099 forms submitted via Turbo Tax?

I received a correction notice indicating that the withholding could not be verified. The state taxpayer assistance group is now saying it will be an additional 6-8 months to review the documents I submitted e.g. relevant W-2 and 1099 forms. I am a long time Turbo Tax user and have never had an issue until now.
