Yes. You can upgrade or switch to a different version of TurboTax after you've started your 2023 return.
To upgrade your version of TurboTax:
Once you’ve paid you can go to Tax Home to access your upgraded features.
If you only need your adjusted gross income (AGI), we can help with that. The IRS also provides transcripts and copies of past tax returns.
Thanks for your response. Does this apply only to the online version? I'm using the desktop version, and see options to upgrade to a different desktop version, but not to Turbotax full service, where an expert does the return for me.
