Update:
TurboTax 2018 won't calculate the reduced amount of interest when your interest deduction is limited.
After entering all your 1098s. TurboTax will then refer you to IRS Pub 936 to calculate this amount and lets you enter that.
TurboTax 2021 is probably unchanged in this regard.
The other tax software I mentioned (privately) is the same but makes the worksheet available in Forms mode so you don't have to wade through the IRS Pubs.
