California Form 5505-Underpayment of Estimated Tax

On California Form 5505 (Underpayment of Estimated Tax) Part III, Line 4, (Annualized Income Installment Method) says:

"Enter your itemized deductions for the period shown in each column. If you do not itemize deductions, enter -0- here and on line 6. Estates or Trusts, enter -0- here, skip to line 9, and enter the amount from line 3 on line 9 "

Why does TurboTax California Form 5505 show itemized deductions on Line 4 when I did not itemize. Line 4 and line 6 should be zero. The input screen for California itemized deductions in the Underpayment Penalty area, shows total itemized deductions and has boxes to fill in the itemized deductions for the 1st, 2nd and 3rd quarters.

IRS Form 2210 (Underpayment of Estimated Tax) handles this correctly and shows zero on lines 4 and 6.
