Negative value transferred to Schedule CA line 8a (Home mortgage interest on form 1098) causing unfixable error.

I am working with 2022 Home and Business.  An error comes up in CA Schedule P(540) Part 1, Line 4.

"Schedule P: Line 4 is too large.  Line 4 needs to be less than or equal to the total mortgage interest and points reported on Schedule CA, Part ll, line 8e."  Schedule CA Line 8e comes from line 8a, "Home mortgage interest and points reported to you on federal form 1098" has a negative value, and I have no idea where that is coming from.  My 1098 shows $4011 interest paid.

Is your mortgage interest split between your residence and a rental property? Did you enter more than one Form 1098? Did you use all your mortgage proceeds to purchase or improve your main home? Did you take the standard deduction or did you itemize?

It appears this negative number has been calculated from one or more entries made under the Mortgage Interest section of Deductions & Credits. You may wish to review your answers to the questions after you enter Form 1098 to be sure the entire amount should be included in the itemized deduction calculation. 

Also review Schedule A, the Tax & Int Wks, and any AMT forms under Form 1040 in the forms list in case the negative number came from a federal form.

I had a similar case in which the Cx had multiple schedule Cs and was including the mortgage interest in all 3.  Once we uncheck to include the in the home deduction it cleared up the errors.
