As you work on your return, we alert you to obvious errors, such as missing Social Security numbers and incomplete forms.
When you go down the path to e-file your return, TurboTax runs a second, more rigorous error check. It looks for subtle things that might cause the IRS or state e-filing systems to reject your return.
(If you're wondering why TurboTax didn't alert you earlier, it's because TurboTax hadn't asked you yet if you were planning to e-file.)
Before you can successfully transmit your return, you will need to correct your return and/or update your program by following the onscreen instructions.
If you have trouble transmitting your returns, we've got some common solutions.
If your tax return can't be e-filed for some reason, TurboTax will let you know.
