Thank you again...I have answered the questions I think correctly this time and the amount of the credit is calculated correctly (without override) and the total on form 3468 is the correct credit amount, but the credit on form 3800 worksheet Line 4a Investment Credit, Part VI (Form 3468) amount is double the 3468 amount. This credit will be carried over but is not being reported correctly on Form 3800.   This taxpayer also has the residential solar credit (Form 5695) and has carryovers.

Any suggestions.

Thank you again.
