Not sure what forms you are referring to, but if you e-filed your return there should be no forms you need to mail.  Also, hopefully your federal return was accepted.

The IRS expects the earliest EITC/ACTC related refunds to be available in taxpayer bank accounts or debit cards starting February 27, 2018, if these taxpayers chose direct deposit and there are no other issues with their tax return.

You can checked the IRS website Where's My Refund for your information?
