CARES act.Has Turbo Tax changed the business interest deduction from 30% to 50% if so I am not seeing it when I enter my interest ?

I'm not sure if that has been update yet. If you are using the desktop TurboTax, have you run your updates?

IF that applies to your tax return, you REALLY should be going to a tax professional.  The change of that limitation is based on a law that only applies to businesses with average receipts/income of over $25 million.  A business of that size should really be going to a tax professional.
