ON a 1099B... gross proceeds less commissions amount of about $3000.00 was paid to me. You go into the history of all the stocks and although I sold them, the total is actually a loss of about $1500.00 over a 3 year period. So on my 1040 after I enter all the individual stocks i.e. date bought, how much I originally paid, verses how much I received it will show up as a loss. Is this correct

Correct - your schedule D should show a purchase cost basis of $4500 and sales price of $3000, for a net loss of ($1500). If you bought the stock 3 years ago, then you have a long term loss on the sale.

Yes, you will report each stock sale on schedule D (Form 1040). If any stock was sold after one year of purchase, you have long term gain or loss.
