I found the answer to this. Apparently TurboTax doesn't like it if you have some special characters in your password for your financial institution. :(
I found this information here:
https://ttlc.intuit.com/questions/1899399-unable-to-import-1099-despite-using-correct-login
"your financial institution's password contains special characters like $ % &".
I don't know exactly which special characters are not allowed as one password had an ! in it and that was ok, but ones I had with #, &, and $ didn't work.
This is very disappointing but if you change your password to something without special characters, you'll be able to do the import. Then you can change it back later.
