1098 for vacant lot loan expected to start construction in the next year

I purchased a vacant lot in 2021 using a " mortgage" loan from our Credit Union. The mortgage  was paid off later last year.  The process for initiating the construction of a home will start later this year.  I have received a Form 1098 ( no suffixes ) from the Credit Union with: Box 1: the interest paid last year, Box 2: Outstanding Balance ( Incorrect since the Loan has been paid ), and Box 3: Mortgage Origination Date.

Can this be used as a deduction on my taxes for 2021?  If so,  where do I enter this information into Turbo Tax?  Typically we do NOT itemize deductions but allow Turbo Tax to decide if we should take the Standard Deduction or go with iemized deductions.
