Installment Sale with no payment in first year

Sold a piece of commercial property (not a main home) with a closing date in 2021 but received no payments in 2021.  The installment Sale proceeds start in 2022.  There was no business associated with the commercial property.  Do I report any of the sale information in the 2021 tax year or do I wait until the tax year when beginning to receive the installment sales income/payments?
