If you bought and sold same security several times in a 30 days period, is it all wash sale ?

[Kkulkev21]

Maybe I don’t understand the Wash sales rules fully. I bought and sold a security at a loss and then within 30 days bought it again and then sold it again at a loss. Will both these losses count as wash sales ? The 1099B from Merril edge only flags some as Wash sale. 

Should I go by what the 1099B says and just enter it as such into TurboTax ?

Also, one of the securities that I bought and sold in Merril (9/6-9/15) at a loss, I bought and sold in Schwab (9/22-9/25) at loss again. But since it was different brokerage, it wasn’t flagged as wash sale. Do, I enter both of these losses into TurboTax as Wash sales myself ? 

Will it better if I just enter summary from both Merril and Schwab into TurboTax and then print form 8453 and mail it with 1099B ? 

I don’t want to do anything illegal.
