It is absolutely still an issue for 2020 returns. We refinanced in 2020 a loan which was originally taken out in 2016 (pre-TCJA). TurboTax is unable to handle the fact that all the mortgage interest paid (to both lenders) in 2020 is fully deductible per IRS rules (https://www.irs.gov/pub/irs-pdf/p936.pdf). Instead, the only way to get it to correctly add up the total deductible mortgage interest seems to be to put "$0" for Box 2 of the new loan.
I am also concerned this is going to be a problem going forward in future years as there does not appear to be a way to tell TT that a loan originated in 2020 is nonetheless subject to the pre-2017 deduction rules as it was a refinance of acquisition debt. Certainly possible I am missing something, but have been trying various strategies for a while now without a good solution.
