You can check to see if your tax return has been efiled by going into this website:
https://shop.turbotax.intuit.com/_intuit/turbotax/efile/efile_status_lookup.jsp;jsessionid=UA0JFdBbu...
If it was efiled then you can do an amended return. You can do it thru TurboTax when IRS comes out with the approved amended Form 1040X on Feb 22nd. It is best to wait until you get your refunds before amending.
