I live in Texas. I efiled my tax return with form 8379. do I also need to mail it

Since your e-filed tax return included the Form 8379 there is no need to mail the form to the IRS.

I filed my taxes already on turbotax and I am trying to find the address to send my form 8379 to. I am from Texas. 

Please see DoninGA's post above. If you have already e-filed and included the form 8379 no need to mail it in.
