The $1 million limit applies, meaning that almost all your interest should be deductible. To get TurboTax to apply the correct limit, make sure you answer Yes to the question Do either of these apply to this loan?
You will see that question after you select Done when you are taken back to the Home loan deduction summary screen. You will then answer the balance as of January 1, 2022 so that TurboTax can determine the average balance of the first and last month.
