adding 100 lines of stock sales with wash sales adjustments? How can I do this?

If you summarize (recommended),

you only need to supply details of 1099-B covered transactions with adjustments that are not listed on your e-Filed Form 8949. and all non-covered transactions not listed there.

In other words, for active investors, generally this is a list of the Wash Sales.
You may supply details on your separate Form 8949, or other document with the same information and in the same manner as Form 8949.

If you have two pages (for example) of Wash Sales,
use Adobe Reader to print those two pages. That's all you have to mail to the IRS, given that those wash sales are not on your e-Filed form 8949 already, assuming the remaining subtotals are on Schedule D Line 1a.
(you might enter them manually if they are few in number.)

If you plan to mail your entire consolidated 1099-B,
put your amounts for covered transactions on Schedule D Line 1b or Line 8b.

complain to your broker, ask them why the won't give you two selectable reports to import:
transactions with adjustments and,
transactions without adjustments.
