I filled out my 2021 tax return on TurboTax, but didn't file it. TurboTax desktop version does not work on my computer. How do I file the return?

You should be able to just print it out and mail it now.  Was it done or do you need to finish it?

How to Access prior year online returns

If you can't get the side menus to open up to access the prior year..... You need to start entering some basic Personal Info in 2024 for the side menu to open up. Just continue a little ways into 2024. I had to go though about 12 screens.

@travisbens be warned that if you are filing a 2021 tax return, 

1) if you owe, you owe.

2) if you are due a refund, the window to claim that window closed on April 15, 2025  They IRS will not send you this money.  However, if you applied for an extension back in early 2022, the window won't close until October 15, 2025.  

Are you stating way back when you began the 2021 tax return using the online version and you never filed it.  Yet you now want to finish this activity, but TT doesn't work on your personal computer?  You have to PURCHASE the 2021 desktop version and load it onto your computer.  It should work!

Can I ask why you are now just filing?
