Tip: Don't confuse
boxes A, B, D, E, and X on your TurboTax screen with the 1a, 1b, 1c (etc.)
boxes on your 1099-B form. These are two completely different things.
Boxes
A, B, D, E, and X often appear as headers or section
titles on your 1099-B form instead of literal boxes. Exact wording
varies between brokerages; for example, Box A from 3 different brokerage
statements might read:
·
Short-term transactions for which basis is
reported to the IRS—report on Form 8949 with Box A checked.
·
Short-term transactions for which basis is
reported to the IRS--report on Form 8949, Part I, with Box A checked.
·
Short-term transactions for which basis is
reported to the IRS—report on Form 8949 with Box A checked and/or Schedule D,
Part I.
Nevertheless,
they all mention Box A, so you'd check Box A in TurboTax and the next screen
will open the 1a–1g boxes which correspond to your 1099-B form. Boxes B, D, E,
and X work the same way.
