You can enter another manufacturer's code and that will get you past the efile issue. But before you do that make certain that the first digit in your code is I as in India and not the number 1. I7Q6 is the code for Daikin.
If that is still bouncing back then save all of your documentation in case there are any questions in the future and you will have to print and mail your return in order to get the proper credit.
