Read the ADOR FAQ's - any overpayment on either 140-SBI or on the 140 - will offset any amount owed on the other one.  The FAQ's came out in April after the court cases killing Prop 208 and validating the new flat rate for 2022.  Of course, when I was filing extensions for SBI clients, we didn't have the FAQ's yet, so I printed an SBI extend form and had the client pay, but that form doesn't exist in ProSeries, so you have to manually enter that on the SBI form.
