@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?
