When did you purchase the home? Illinois property taxes are billed in arrears. That's means that the property taxes you paid in 2020 are for the year 2019.
You may figure a credit for Illinois property you purchased during 2019 providing you figure only that portion of your taxes that pertains to the time you owned and lived at the property during 2019. You may not take a credit for taxes you paid if the seller reimbursed you at the time of closing. You also may not take a credit on your 2020 return for property you purchased in 2020.
You will be billed for your 2020 property taxes in 2021. Property taxes are deductible in the year actually paid.
