The TurboTax software will be updated to the 2021 contribution limits after the IRS finalizes the forms, schedules and instructions for the HSA contribution limit.
The IRS has most all 2021 forms, schedules and instruction in draft mode and will not finalize until January and February of 2022. Go to this IRS draft form website - https://apps.irs.gov/app/picklist/list/draftTaxForms.html
The availability dates of IRS forms will be shown using this TurboTax support FAQ sometime in mid-December - https://ttlc.intuit.com/community/forms/help/irs-forms-availability-table-for-turbotax-individual-pe...
