You will get a email stating your returns were transmitted, then you will get an email letting you know if your returns were accepted or rejected. If you are due a refund, there is no penalty for filing a late return. If you owe taxes, then you will receive a bill for the penalty & interested owed.
If your returns get accepted & you have a refund, you can check the status of your Federal refund on the IRS website Where's My Refund
