If you need to amend your return, you would need to wait until it's either been accepted or rejected. If it's rejected, you can simply go in and fix the error, add the additional 1099 and 1095 and re-submit your return. If it's accepted, you would want to wait until you receive your refund to amend. Please see the FAQ link provided below for more information on when amendments will be available:
