See this TurboTax support FAQ for completing a 2021 tax return originally started with the online editions - https://ttlc.intuit.com/turbotax-support/en-us/help-article/printers-printing/finish-prior-year-retu...
A 2021 tax return can no longer be e-filed using TurboTax. You will have to print, sign, date the tax return and mail the tax return to the IRS.
If you paid for the online edition with a credit card you will need to contact TurboTax support so they can push a 2021 installation file to your download account at no charge.
