After entering 1099-B manually in summary form, TTH&B tells me I cannot e-file

I entered my 1099-B manually in summary form (There was a net loss if that matters.) and TTH&B says I have to mail a paper copy of my return to the IRS.  If I delete that (manual) entry and import the data from the financial institution (FI) ...
(1) will I still have to mail the return to IRS?
(2) do I have to mail all that paper to the states? (there are two of them because of an unrelated farm in a second state)
(3) does Intuit store the password to my FI account?
(4) what else does Intuit do with my password?

Thank you.
