WHile other entities may be accepting e-filed returns, they IRS is *NOT* and will not until the end of january at best. Could be later. So if you submit a return now, all it does is "SIT THERE" until the IRS pulls it. So if it's sitting there and you need to make a change, you can't do squat until the IRS pulls it and "IF" you're lucky, the IRS rejects it. If the IRS accepts it, then you have to wait until they process it, before you can amend the return. Add to that, amended returns can not be e-filed. The IRS says so. You have to print, sign and mail the return to the IRS. To add even more to that, since amended returns are processed by hand it can take 6-12 weeks, and usually longer for them to process it.
If you were to e-file your return with TurboTaxc right now, then you're locked in until the IRS starts pulling those returns. Heck, there was one year where the IRS didn't start taking e-filed returns until the third week of Feb.
