NO. Stop. You can not add more after you file. You need to do an Amended 1040X return. So take out anything you've added. The after the IRS is done processing the first return and you get the refund, then you can amend. You have to start the amended return with the return that was accepted. Oh the amended return won't be ready until Feb 15.
