Intuit loaded an update over night. This seems to have fixed the efile problem. I was able to submit federal and state taxes using efile this morning, 02/15/24 ...
I suggest that people with this problem call Intuit customer service at800-446-8848. The agent I spoke with was very pleasant but had no idea about this problem...
As of 02/12/24, I still cannot efile with IRS form 7602. Have updated TT Business running on Windows/Chrome. I sent diagnostic report with number 1180217.
