> Do NOT use this online form if you're required to file a tax return. Use of this online form creates a simplified 2020 tax return. If you're required to file a tax return but file a simplified return instead, you won't be able to e-file your 2020 Form 1040 or 1040-SR tax return. This will delay the IRS processing your return and issuing any tax refund.
So... what?
Do not use this site if I'm required to do the thing that this site does? If I use this I won't be able to e-file Form xyz? No information what those are, or why it would matter?
