Can i start my granddaughters return over and complete as hers keep getting rejected?

It depends why it is being rejected whether it can be electronically filed. If she has already paid any fees, then no, it could not be cleared. 

I recommend trying to identify why it is being rejected using any rejection codes provided.

Please click this article for Troubleshooting E-filing Problems.

Also, double check if the error is from the state return. Some states require a driver's license to file electronically, for example.
