I screened shared with Intuit Agent Vanessa and she was unable to assist. She claims it is a known issue by their engineers. I told her if Intuit can't fix it within a week I will request a refund on the product.
It was not anything I had entered as Intuit updated the program and I no longer getting the Validate Error, but alas the Financial Institution 1099 import is still not working for brokerages. See my latest update of 3/1/2021.
