Thanks Mike; yes, I paid for "Live Support" and TurboTax is referring the issue to an AMT Specialist after the Tax Specialist and I discussed the issue at length and found no resolution. Either it's a programming error in TurboTax OR the AMT rules/regs/court rulings somehow deem the NON-passive losses of renting-one's-own-home pursuant to Instructions for Form 8252 (i.e., the dwelling where one lives for more than 14 days during the year) to nevertheless be "passive" for AMT....Other TurboTax customers may be getting incorrect results and erroneously paying the AMT... will keep you "posted"....Thanks again.
