there are several ways to handle summary totals
codes A or D with no wash sale can be entered as separate totals on the 1099-B workshet in the section labeled Form 8949 reporting exception transactions (not sure which versions have - certainly all desktop versions)
these flow to lines 1a and 8a of schedule D. no setails have to be provided to the IRS.
other transactions; types B, C, E, F or any that are type A or D with adjustments; need to be separately reported on form 8949 unless you group them by type.
Then you must enter code M that indicates to the IRS you are reporting multiple transactions on a single line.
If you do this you are required to send the IRS details of each transaction s reported on the 1099-B. this can be done by using form 8453 - see instructions - and mailing it with the supporting details
