I'm currently getting an error on my federal review telling me that I need to enter a number in a line titled 'Limited amount to report on Sch A, line 8a' but no instr.

instructions.  

We bought our main home last year in early 2019.  We then refinanced the original purchase loan in late 2020 solely to drop the interest rate.  

The federal review error is taking me directly to the form and want even let me see what 'line 8a' even is.  Need some help here
