Hi,
My Financial company sent me a 1099-B with the following "short term basis not reported to IRS".
I am creating individual stock list (instead of sum up).
(1) Do I need to submit form 8453 along with a copy of my 1099-B?
(2) Even on form 8453 (https://www.irs.gov/pub/irs-pdf/f8453.pdf), I don't see 1099-B in the list to check on.
Please let me know.
