No, you cannot e-file a second Form 1040X. And just hold on. Why are you amending a second time? and why now? You should not amend a tax return until your original tax return has been fully processed. So when you amended for the first time---had your original return been processed completely?
It takes the IRS at least six months to process an amended return, so if you have a good reason to amend again you need to wait until the original return AND your first amended return have been fully processed before you try to put another amended return into the system. You have three years from the filing deadline to amend, so you have plenty of time to amend if you really need to. Do not confuse things now by trying to put another return into the system or it can cause confusion and delays that will seem neverending.
