it depends on what version of Turbotax you are using. I don't know what's available in the online versions. in desktop you can go into forms mode and enter all type A transactions with no adjustments (short term - sales price and tax basis reported to IRS) as a single number on form 1099-B worksheet in the section labeled Form 8949 reporting exception transactions. No details need be sent to the IRS. the same is true of type D
********************
for type a and d with adjustments and all other types, the details must be furnished to the IRS by entering each separately on form 8949 or entering totals (using code M) and using form 8453 (Turboxtax supports this and entering code M should generate this form with the box for Form 8949 checked). submit it with detail to the IRS through the mail
***********************
8453 instructions
If you are filing your tax return using an online provider, mail Form 8453 to the IRS within 3 business days after you have received acknowledgement from your intermediate service provider (ISP) and/or transmitter that the IRS has accepted your electronically filed tax return. If you don’t receive an acknowledgement, you must contact your intermediate service provider and/or transmitter.
