If you have already entered Calif withholding on a 1099-MISC, TT/Calif will not ask you to fill out a 592-B. It's only when you enter Calif withholding in the federal return under Other Income Taxes Paid in 2017 / Withholding not already entered on a W-2 or 1099 that it will ask about that and/or Form 593.
Or, if you told TT/Calif that you had a 592-B to enter, then delete it - that may make the message go away. In Forms Mode, if the 592-B is shown in the forms list, open it and click the Delete Form button.
