You can use the TurboTax online editions for tax year 2020 - https://turbotax.intuit.com/personal-taxes/online/
If you used the TurboTax desktop editions for tax year 2019 you can transfer the 2019 tax data to the 2020 online tax return.
See this TurboTax support FAQ for transferring prior year tax data from your computer to the current year online editions - https://ttlc.intuit.com/community/entering-importing/help/how-do-i-transfer-last-year-s-return-into-...
