Since all your trades were short-term, and you're not dealing with wash sales, only two lines are needed on your Schedule D, Line 1:
col a: Scottrade col b: Various col c: Various col d: Total proceeds from Scottrade col e: Total cost of Scottrade stocks
col a: Harmon col b: Various col c: Various col d: Total proceeds from Harmon col e: Total cost of Harmon stocks
column d amounts should match total proceeds on 1099-B's you'll get from brokers.
Deductions not related to particular trades are likely investment expenses (reported on Schedule A, Line 23) - except investment interest expense, which goes on Form 4952.
