If I refi'ed in 2019 for $1Million, how does TurboTax know that refi was for a house purchased many years ago and that I am grandfathered to get a deduction up to 1Million and not just 750K? The 1098 only states the mortgage origination date and nowhere on TT does it ask when you originally purchased your home. I obviously want to make sure I get the full deduction and that TT doesnt think that I purchased my house in 2020 which would only give me a deduction of up to 750K.
