I discovered that the 2020 tax return I filed with Turbotax is different to the one my state received and I am being audited. Worse - I can't get speak to someone on TT.

I received a proposed audit of changes from my state. However, when I downloaded my state returns from Turbotax and spoke to someone at my state tax department, I discovered they were different resulting in a large bill. And it's an insidious loop, online or on the phone to speak to someone on TT. Never experienced anything like it.
