I mailed my taxes in but forgot to include form 8332 the Release/Revocation of release of claim to exemption child by custodial parent. how do I add it?

Form 8332 is handled separately from the e-file.  It cannot be electronically transmitted or attached to an e-filed return.  The non-custodial parent must mail it, along with an IRS Transmittal Form.  (The tax return can still be e-filed, just not the Form 8332.)  

The custodial parent will print and sign the form, then deliver it to the non-custodial parent who will then send it to the IRS along with the Transmittal Form (form 8453).  

The transmittal form can be found here: https://www.irs.gov/pub/irs-pdf/f8453.pdf

The non-custodial parent will mail the transmittal form along with the signed Form 8332 within 3 business days after acknowledgment that the IRS has accepted the e-filed tax return. 

Mail Form 8453 and 8332 to:
