I waited a few days and tried again - it failed again. I then had the idea to delete the small 1099-INT item and to move it to a line item in business income in the hopes that the Form 8960 might be removed automatically by TT - it wasn't. I went ahead and tried to re-file and it was rejected again. I guess I'm waiting until there's a know fix by the IRS. I did go back and put the interest income in the right place again so it will be ready when the error is resolved.
