You do need to file the form 1099-B information. The IRS will tax you on the entire proceeds if you don't include the cost basis information on your tax return.
You can make summary entries for your categories of income (Code A,B, etc...). As long as you get everything summarized correctly with respect to short term versus long term you should be OK.
If you choose to do the summary entry, you should mail in your tax return and attach a copy of the detail of the investment sales however.
