If by "this year" you mean you sold the property in 2019, you also have to take into account the depreciation taken in 2019 (which will not be included on the 2018 IRS Form 4562). As of this date (Dec 30, 2019) the depreciation section of the program is still under construction. So you'll have to wait for that section to be completed before you can get the exact amount of depreciation recaptured and taxed.
