I've done my homework and have waited for Proseries to update 2018 program for the MIP deduction, but nothing yet.

As you can see, it was changed in December of 2019, retroactive back to 2018 taxes.  Maybe you should do your homework before trying to make an ass out of a fellow tax preparer who actually was correct and you were not!!
