Can you please specify what part of the CA return the program is stating you need to fix?

medical and dental expenses.  Line 4 specifically, which should be line 1 minus 3.  The number that automatically got filled is too high, when I input the correct number and hit continue, I just get stuck in a loop.

I am having the SAME EXACT ISSUE. If anyone has got this figured out, I'd love to hear it. Line 1 and line 3 are correct, and when subtracted should have a different number than line 4 has auto generated. But when I try to correct this line, it won't save, and sends me back to the original page. I've re-entered all of my medical expenses and double checked that any expenses that weren't paid have "0" entered, still not working. This is under the CA Adjustments form, Part II lines 1-4. This seems like an issue with the website itself since the numbers are correct but the auto-generated total isn't.

I'm having the same issue as well. The info in the interest section of my form is correct, but it keeps asking me to fix it.
