I am baffled by the fact that this worksheet is useless. Like others have said, the MFJ return has all the numbers, so it should have no problem telling me if we're better off filing MFJ or MFS. It would be awesome to save some time and be able to trust this What-If Worksheet, but instead we have to create 3 separate returns to do this. When comparing the tax payer's MFS return to the What-If Worksheet in MFJ return, it's literally showing me a difference of owing $4K vs owing $12K, respectively. Utterly ridiculous!
Am I correct in that this feature was just introduced for TT 2024? I don't see it in 2023.
