I ended up reaching tech support who did a Glance session. She went into Internet Explorer and, I believe, added a bunch of intuit websites to the safe sites. I thought she'd de-selected "enable protected mode" but when I opened it just now to check, that was still selected. She did not make IE my default browser. Anyway, so thank you for the response. Some aspect/setting in IE was definitely the problem and it is now fixed. Thanks much!
