If u have an offset will they send a letter first letting u know that this will take action

You will be contacted by mail (not by e-mail or phone) if your refund is being offset.  You will most likely find out by tracking your tax return first though.  It will show on the IRS Where's my refund site if your refund is being offset.  

Please see the following TurboTax FAQ for information on this:
