Get your taxes done using TurboTax

Form 1098 Box 2 for my construction loan is blank.  Although it was originated in 2020, the first draw did not occur till March 2021 where a principal was incurred.  Subsequent draws increased the principal up to the final value in June 2021.  Turbo Tax wont let me leave beginning principal as 0, what should it be reported instead? the 1st draw principal or the final principal value?
