I followed these instructions, I'm actually not getting an error message, but when I check the box that says I need to limit my mortgage interest deduction, it never takes me anywhere to do that. When I navigate back to the 1098 screen and click continue the check box has reverted back to "none of these situations apply to me".
EDIT:
I believe I need to edit box 8a on my schedule A form, I was able to do this last year, after I calculated my mortgage interest deduction limit using an IRS worksheet. The question Turbotax asks here is really misleading because it implies that if you have mortgage debt before Dec 2017 and after Dec 2017 that you only have to care about the average balance of the loans before Dec 2017 being less than 1 million and the loans from after Dec 2017 being less than 750,000, but that's not true.
