If you qualify as a Real Estate Professional AND you Materially Participate in the rental activity, yes, any losses can offset other income.
However, that does NOT make your prior Passive Loss Carryover usable. That can only be used against passive income (or income from your formerly passive rentals). TurboTax is NOT set up for that, so you will either need to figure out a work-around or go to a tax professional.
Your current-year losses would offset any other current year income (such as your wife's income). If the losses are larger than your current year income, yes, you may have a NOL that can be carried back to 2015.
No, there is no limit for the NOL (including based on bonus depreciation).
Yes, the NOL may affect AMT. However, TurboTax does not calculate NOLs at all, and I think AMT NOLs are even more problematic. If you have an NOL, you may want to go to a tax professional, especially if you subject to AMT.
