CPAs have a legal responsibility to exercise due care for their clients. AI lacks any of this. Use a local CPA and be done with it. It sounds like you can afford the couple hundred dollars at most it costs for their services.
So, while they might have a legal responsibility, it doesn't mean they necessarily fulfill it. And in the end it is my time and money and stake.
Sounds like your "well regarded" CPAs are awful. Time to find a competent one.
