I need to amend my 2021 return but when I click on the Turbotaxreturn.tax2021 to open it in TurboTax Desktop2021, it gives me an error message 190. I've attempted this multiple times.

Error 190 occurs when your 2021 data file contains a state return, but the state program for that state is not installed in the 2021 software, so TurboTax doesn't know how to handle the data file. To try to remedy that, launch 2021 TurboTax and start a new dummy return long enough to download the 2021 state program. Once the 2021 state program is incorporated into your 2021 desktop program, TurboTax can then open the 2021 data file containing a state program. Also see my TIP below for the best way to open a data file.

TIP: While clicking (or double-clicking) on the *.tax2021 data file will normally launch the 2021 program, it's not recommended to open it that way. It's best to launch the 2021 TurboTax program first, and then open the 2021data file from within the TurboTax interface. If using the Windows version, once TurboTax is launched, and you are at the TurboTax initial landing screen, go to the top left corner of the TurboTax program interface and click on FILE, then in the dropdown menu choose OPEN TAX RETURN. And then choose the data file to open. The next time you work on the return, after you launch TurboTax program, at the landing page there should be a rectangular icon, which is a shortcut to the data file. So on subsequent uses, after launching TurboTax you can click on that rectangle to open the data file.
