How do I enter a CA 2017 State Income Tax Refund reported on a 2020 Form 1099-G in TT2020 H&B desktop?

For received Form 1099-G details entry in TT2020, Box 2 ("State or local income tax refunds, credits, or offsets") shows an amount refunded and Box 3 ("Box 2 is for tax year") shows "2017".

In TT2020, the 1099-G form forces linking out to "Federal Carryover Worksheet" but it is unclear how to enter the refund and year or link it back to the 1099-G. Any help would be appreciated.
