The TurboTax online editions for tax year 2019 should be available in early December.
Do not rush to file your tax return. The IRS will not be accepting any type of 2019 tax return until late January. Those that file early and before the IRS opens have a better chance of having their tax returns not processed immediately than those returns that are filed after the IRS opens for filing.
And don't file early! Last year the IRS put out some late changes and some early filers got tax due notices after they got their refund. Also if you file in an early batch they get stuck in processing and might even take longer to get your refund.
I had no idea about filing too early! Thank you, that was very helpful!
