Apparently the Self Employed DIY version of TurboTax has click throughs that show how to calculate the recapture, but there is no worksheet to do more than asset, or transfer totals automatically to the Form 4797 Part IV that is apparently required, so now I will have to file an amended return once I figure out how to get this done.  Is there a way to upgrade after paying and filing? Why not suggest that before I file an incomplete return?? Anyone from TurboTax monitoring here?
