My brokerage provides tax package with a summary at the top for each account, so I see the 1099-DIV, 1099-MISC, 1099-B, and 1099-INT key info at the top (I'm assuming this is how it's done in general). These are the numbers I refer to in order to complete my taxes, and this has worked fine in previous years. All 3 accounts have 0.00 for boxes 8, 9, 10, 11 as I look at my paperwork. TurboTax, however, has imported information that indicates gains and losses.
I'm not sure whether this means that I can't trust my brokerage, or whether I need to just delete everything that TT has imported and fill it in manually. (If I try to edit, it provides every little detail and I just am not in a position to evaluate all of that, especially as it's likely unnecessary.) Has anyone else run into this?
TurboTax imports the complete statement not just the summary info at the top. So there may be more information on the statement if you dig into it further. TurboTax does not invent information to fill in to the other areas so it has to have come from the imported statements.
If you choose to import again, beware of duplicated records now on your tax return.

What Box Categories do you need to report.
Regarding stock and options, those are covered transactions and the broker reports them for Box A; Lines 8-11 are not applicable.
Detail Reporting Exception: if you summarize Category A or Category D, Form 8949 is not needed for transactions without adjustments. No mailing is necessary. No attachment is necessary.
As an active investor, be aware that your category Box A or Box D sales without adjustments do not require Form 8949, so there is no reason to import or key in those transactions.
Instead use the "enter a summary" option to put your numbers on Schedule D Line 1a or Line 8a.
No mailing is necessary.
If you have wash sales, it gets more complicated since those adjusted transactions have to be itemized on Form 8949 and the summary totals adjusted accordingly.
