Investors & landlords

So this has been an issue for several years now.  TurboTax automatically calculates everything else automatically for me.  Wealthfront had a calculator last year, so we know it can be done.  Why can't TurboTax have a calculator for this and just let me enter my information and then TurboTax calculate it like they calculate everything else? I am paying TurboTax to be the expert so that all I need to do is enter information, but nope...not on this issue.  Why?  This is a serious question that I would love to have answered by someone from TurboTax.
