In the future, buy the download version of TurboTax, rather than using online TT (TTO).
If you used the download (or CD) version of TurboTax (TT), that is, you currently have TT 2021 on your computer, make a copy of your 2021 return (click file / save as). Name it something like "2022 Preliminary" and then replace your 2021 entries with your 2022 estimates. It won't be exact because the program uses 2021 tables and numbers. But, it should be close enough for most purposes. I use the override feature to change the standard deduction and MAGI numbers, on the forms, where appropriate. This doesn’t work with online TT, because you will override your 2021 return.
