You will enter the actual amount as listed under the California column on your Schedule K-1. TurboTax will calculate the difference based upon your entries.
You should make the entries in the California interview screens though to ensure everything pulls into your forms correctly. This will be done by select edit to the right of the applicable Schedule K-1 and proceeding through the screens until you are given the option to enter the California amounts.
All that I receive are pages in addition to the K-1s that are titled "conforming" and "non-conforming" states. Most of the time, the entries under California are blank or a few dollars. From other articles, I have learned that some people receive an additional K-1 specific for their state. I don't. So can I ignore the entries on the extra pages? If not, do I enter the positive/negative amount listed on those pages (usually it's a few dollars, at most) or add/subtract the amount listed on those pages from what is shown on the K-1, and then enter that amount under my state in the program? Nothing in the K-1 instructions addresses this issue.
