Get your taxes done using TurboTax

I received a 1099k from Paypal because I sold over 200 things on EBay.  Most were for just a few dollars.  Where do I report the income from these sales on my 1040?  Then where do I report the expenses?  Some of the money on the 1099k include what the customer paid me for the postage so my postage is an expense.  These are all items that I sold from my home - like a garage sale. 

Thanks!
