I forgot to add my 1098-e what is going to happen

[ddaven12]

Nothing will happen, you will be fine. Once your tax return is filed you need to first wait and see if your tax return is accepted or rejected. If rejected, you can go back and add the 1098-E and then re-submit your return.

If accepted, you need to wait until you receive your tax refund and then Amend your return using Form 1040X. The form will be available sometime in February. 

Here is an FAQ with additional information on Amending: https://ttlc.intuit.com/replies/3288565
