Despite various cost-of-living thresholds being published by the IRS more than a year prior to the release of the corresponding year's TurboTax, the initial release always still shows most of the the previous year's thresholds. This is a problem every year. It's inexcusable.
Since you are using the CD/download version of 2020 TurboTax, you can use overrides to make the correction until the developers make the correction. Corrections of these cost-of-living adjusted values are typically accomplished by early January, most of them by sometime in December.
