Thank you for asking this question! I am in the same situation, I refinanced my home two times in 2020 and received three 1098s. Each loan balanced was moved from two mortgage companies and onto my current mortgage company, taking out no cash in the process.
Turbo tax says: "Enter your loan balance as of January 1, 2021, or the final principal balance if you paid off this loan in 2020". That would leave me to believe that even if you refinanced it, it is asking for the final amount before you moved it between lenders.
However, if the expert above is correct, then that sentence is only applying if you actually paid off that loan and have no new debt. So if you refinanced the mortgage, enter $0 as there is no longer a balance and ignroe the second part of that sentence.
TURBOTAX please rephrase that sentence, super confusing.
