It seems this is a software bug that is unable to correctly handle refinance of Jumbo mortgages taken before Oct 2017.
If I read this correctly what you are suggesting is to report two 1098's (original and refi) as one 1098 by adding the interest values and using the original loan amount / origination date. Is this compliant with IRS guidelines i.e. reporting one 1098 while actually having received 2? what if you get audited ?
Although this workaround can correct the return value I can see how it will create problems going forward. next year the 1098 issued by the lender will have the refinance date in BOX 3. the software will then again cap the deduction amount to 750K limit not being able to account for the refinancing. How is this going to be handled and why can't turbo tax software simply fix this bug while correctly entering two 1098's?
thanks
