there are seven categories that can be used in Turbotax where only the totals for each category are entered. then you go the 8453 route by sending the IRS the 8453 with the 1099-B attached - no need to fill out forms 8949 for what you end to the iRS
Mailing to the IRS would be annoying if the 1099-B was 100s of pages.
the 6 categories are how Scwab's 1099-B is organized.
A. short-term sales price and tax basis reported to iRS. in addition, if there are no adjustments this can be reported on line 1a of form schedule D and no detail needs to be furnished to the IRS
B . short-term sales price but not cost basis reported to IRS - the iRS wants details
C. short-term neither sales price nor cost reported to the IRS - the IRS wants details
D. long-term same rules A but if there are no adjustments they can be entered on line 8a of schedule D which does not require details to be sent to the IRS
E and F long-term same rules as B and C for short term
X Schwab knows neither the holding period nor their ax basis. - you're the one to make the decision as to how to report them
