My 2020 taxes were rejected and and I'm (finally) getting around to working on it. What do I do?

it can no longer be e-filed. you must print out the returns and follow the Turbotax filing instructions.  this would include attaching any w-2s or other forms with federal withholding.  the same would apply to any state returns but the other forms would only be attached if there was state withholding or the Turbotax filing instructions said to attach them. Sign and date.  I would use a tracking service when you mail them so you can get confirmation, they got to the tax authorities. the federal return goes to the IRS and the state return goes to the state.

If you do not have a copy of Turbotax installed on your own computer, you will have to get one.  You can either buy it from the link at the bottom of the page (products for prior years) or, if you paid for turbotax Online, you can call customer support to get a copy of the downloadable program to install.  You also need your tax data file.  If you were using the desktop program, you already have it, and if you were using Turbotax online, you can download it from your account.

Turbotax online can only prepare the current filing season (2022). 

If you owe tax, you will also owe penalties and interest for late filing.  If you are due a refund, it will be paid with a small amount of added interest (calculated from the 2020 due date, which I think was extended to May 15, 2021).
