How to deal with error created by a turbotax bug after you file?

[jjmg2k]

I filed unusually early this year, a couple of weeks ago in fact, and my return has already been accepted by the feds (I was unable to file my state taxes yet). I discovered after filing that a bug in turbotax had caused it to mis-report one of my sources of income (in particular, it reported only about a third of my rental income for the rental property I've owned since 1996; this is not something it's ever made a mistake with before).

How do I handle this? I tried to amend right away, but the 1040-X form wasn't going to be available for a couple of weeks (it was supposed to be the 19th, but when I checked on the 19th, the date had been moved to the 25th). In addition, I'm seeing advice in this channel saying not to file an amended return until *after* you get your refund. If I do that, I'll be liable for penalties and interest which will be because of the turbotax bug. As far as I know, Intuit won't pay those. I would much rather amend before April 15th (which is something I've done before; there are no penalties for making mistakes before the 15th).

Also is there a way to *report* a bug like this?

It is understandable to want this corrected asap. 

Although the IRS does recommend waiting until your original return has been processed, you can choose to file your amended return sooner, and definitely before April 15th, to potentially avoid additional penalties.

Since the Form 1040X is not yet available through TurboTax, you can choose to wait until it is, which currently is scheduled for February 25th, or download a Form 1040X and mail it in. 

However, an e-filed amended return will be processed faster than a mailed amended return.
