I want to make sure I'm reporting ERC refunds correctly.  My understanding is we report refunds from 2020 Q2 through 2021 Q3 received in 2025 on the 2025 return (1120S in my case).  The credit is reported as "other income" instead of reducing wages expense and is taxable only to federal.  The interest received is reported as interest income and is taxable to both federal and CA.
