Edit 'Deductible Home Mortgage Interest Worksheet' for CA 540 return

TurboTax does not accurately calculate the mortgage interest adjustment for California returns when one refi'd a mortgage (mortgage acquisition date) originated in 2016 in 2020 with a mortgage above $750,000. This problem is very well documented and TurboTax just hasn't fixed the issue. Once can override the adjustment in the California return, but then the worksheets are still innacurate and don't support the adjustment.

I need to make adjustments in Part I of the 'Deductible Home Mortgage Interest Worksheet'. It has the mortgage that was outstanding at the beginning of 2020 outstanding for 12 months, and then the mortgage that refi'd and repaid the first mortgage's O/S balance in full outstanding for 5 months. Hence TurboTax adds these two balances together. I need to adjust the first mortgages outstanding period from 12 months to 7 months. I have paid for an online subscription. When going to downloads area to find the desktop version it does not allow me to download it because, presumably, I haven't paid for it. How can I make these adjustments in Part I of this workseet in the CA 540 return?
