Thank you for your input this, I have been going around with this for hours trying to find out how to get past this error, and your solution worked...but now I am now having a problem with of where to input the solar purchase for a rental and have the credit populate to form 3500. I input the purchase basis in Part VI Energy Credit under Section 48, Section B but I have to override the % to get the credit on form 3468, the final total is correct on form 3468 but the credit on form 3500 is double.  Any input will be appreciated.  

I am using Pro Series.
