I actually went back and looked at the 2019 TurboTax version, and there you have to manually calculate and enter the adjusted amount of mortgage interest that was deductible due to the $1M/$750K limits and the shifting timeframes.
For the 2020 version, they appear to be trying to automate this to make it a little easier. The new form "Ded Home Mort" did not exist in the 2019 version. It appears that it is faulty though and will need some updates if it is to work correctly. One may be able to manually adjust it on the Schedule A as well, but I am not sure.
Turbotax team: Please fix the bugs on this new worksheet!
