I asked a similar question earlier. Previously, Congress had allowed the "Tax Extenders" to expire, which allowed MIP to be deducted. However, on 12/20/2019, the President signed a bill into law that allows for this again (includes for tax year 2018, as well). Hopefully TurboTax will update their software with these changes soon so we can file/amend 2018 with these new deductions.
