Where is beginning principal on 1098?

[Carl]

Box 2, and it's not called Beginning Principle. It's called Outstanding Mortgage Balance. Maybe your lender sent you an outdated form? See the correct form at https://www.irs.gov/pub/irs-pdf/f1098.pdf

Turbo tax is asking for the beginning principal

I don't see that in my H&B version. Did you perhaps originate this loan in 2018? Weather you did or not, just enter how much you borrowed when you did originate the loan.
