Credit for solar panels - S Corp - how to get the 3468 to calculate??

[Username is two words]

The S Corp bought solar panels. Trying to get the credit.  I enter the amount that qualifies on the 3468 worksheet. It does not get multiplied by 26%. If I try to enter 26% of the cost in the left hand column, there is a diagnostic that it's a "calculated field". How do I get the credit to calculate?  Thank you!

Bought them and installed them where? Are they for generating to the grid, or for powering some property specifically?

In the US. Actually, although it did not look like it calculated anything on the screen, the K1 did print the correct information.

Thanks for your reply.

"In the US"

Okay..

Installed them in the US is fine, but the US Tax Code discusses Residential or Commercial, and Producing electricity for sale to the grid vs Producing for Usage or for Storage. Or, to power your lawnmower charging station, or your EV port in the garage. Or, for Hot Water production.
