For a long time TurboTax did not support Line 1a and 8a.
A couple of years ago, TurboTax changed the processing of Form 8949 in an undocumented way.
TurboTax takes advantage of "Detail Reporting Exception" rule and silently suppresses some line items in Box A or Box D category.
Based on prior forum complaints about this. it's not clear exactly what rule it is using, and there is no way to force TurboTax to list all transaction details on Form 8949, as allowed by IRS.
Processing in latest version of TurboTax may be different.
You want to use the "Detail Reporting Exception"
If you got your desired result in a straight-forward manner,
you should post the solution.
