State tax filing

Do not understand AmyC advice below re TurboTax saying there is an underpayment penalty due even though 2108 CA est tax was paid on time.  Advice points to the Federal section "Deductions & Credits" but MY copy of TurboTax Business version shows ONLY "Deductions" and nothing about "Credits".  AmyC advice points to "Estimates and Other Taxes Paid" but NO such entry area exists in my copy of TurboTax Business.   My copy shows a section for "Taxes & Licenses" (and that page lets me enter my CA est tax payment OK, but I'm still getting TurboTax telling me I owe more to CA.....)

 

How do I solve MY problem with TurboTax making an underpayment penalty estimate?
