After you file

Thanks Mindy! So even though 10 of the 30 items were sold at a "gain", I'm still ok to just select "all items sold at a loss" and move on? 

Also, I read a bunch of places that you can get into IRS trouble if you report it as a "summary" netting in your losses and gains? Isn't that what i would be doing here? Do I still have to enter each of the 30 items separately showing what i paid and sold each for? That is what made me pay tax before when i did that.  Sorry for the extra questions and I really appreciate your help, advise and time! Thx!
