I already file one of my w2 this one I already get the refund back to my account. But I just found another w2 from another job. So I cannot e-file for the second w2. Now I file by mail what I have to

You do not start a new return for the second W-2 but have to amend your return to add the second W-2.

Please see the following TurboTax FAQ for instructions on how to amend your tax return in TurboTax.
