My taxes will change significantly in 2022. How do I do a fake tax return to see what my taxes will be like in 2022?

TurboTax's TaxCaster may be of some help

You appear to be using the TTax On-Line version.  Unfortunately the on-line version does not support a 'what-if' scenario (that is only available with the desktop version).

Once you make ANY changes to the online version the previous information is overwritten and is PERMANENTLY deleted.
