How do i prepare 2022 and 2023 tax projections?

Tax year 2023 cannot be prepared until after December 31, 2023.

For tax year 2022 you can use the TurboTax calculator to estimate a tax refund or taxes owed - https://turbotax.intuit.com/tax-tools/calculators/taxcaster/

As for 2023.......we cannot predict possible tax law changes that could be enacted by Congress for 2023.   We have to wait and see what they do during 2023 that might change things.   You will not file a tax year 2023 return until early 2024.

You can used the fully functional 2021 downloaded program to estimate the 2022 tax year  and then the 2022 fully functional program to do 2023 estimations.
